I love the look of this formation on paper. Given how cluttered the Heavy Support slot is for Orks, this provides a way to spam Battlewagons without eating up valuable slots. However, it's also very expensive and I end up being unable to afford the points on anything in the Heavy Support section anyways after filling up the wagons. However, here is a list I have come up with that provides a lot of fast moving armor to threaten my opponent early. Horde Detachment is strictly for the 3rd HQ so that the Meganobz + Boss get a quasi-invulnerable save.

HQ:
Warboss w/ Mega Armour, Da Lucky Stikk (125 pts)
Painboy w/ 1 Grot Orderly (55 pts)
Big Mek w/ Bike, KFF (110 pts)

Troops:
10 Grots (35 pts)
20 Boyz w/ Shootas, 2x Big Shootas (150 pts)
20 Boyz w/ Shootas, 2x Big Shootas (150 pts)

Elites:
5 Meganobz (200 pts)
15 Tankbustas w/ 3 Bomb Squigs (210 pts)
10 Burna Boyz (160 pts)

Fast Attack:
5x Deffkoptas w/ Rokkit Launchas (150 pts)

Formation:
5x Battlwagon w/ Ram + 2x Rokkit Launcha (125 pts x 5 = 625 pts)

No Force Org:
2x Mek (30 pts)

Total: 2000 pts

Thoughts:
Warboss + Painboy + Meganobz in Wagon1, flanked by Ork Boyz in Wagons 2 + 3. The BikerMek + Deffkoptas Scout up behind the 3 Wagons on the board and provide them the 5++ to make sure they get where they needed. The Boyz will stop within Shoota range and allow the Boss to continue forward while also providing support shooting. Tankbustas + Burna Boyz go in Wagons 4 + 5 and Outflank my opponent to limit mobility and flush out the back field units while also providing an anvil that the other 3 Wagons can smash my opponent against. Meks go in the Outflanking Wagons to provide more survivability and keep the Wagons moving. Obviously Grots will sit on a backfield objective and huddle in a building someplace.

I am unsure about a few things though, and that's where I am looking for more feedback:
1) The extra Rokkit Launcher on each Wagon is one of them. 1 weapon is required to ensure that the Weapon Destroyed isn't an Immobilized vehicle, but if I trim off one on each then I can save some points. I lose a little bit of shooting, but ideally it won't be too detrimental.
2) Meks are just a points fill, as well as the Grot Orderly, that could get me another 10 Grots to sit on an objective.
3) I feel like I could drop the Meganobz down to 3, and save 80 pts that can go toward bringing a unit of Lootas to provide support shooting or to add another fast threat in the form of Bikers that will be able to keep up with the rest of the army.
4) Shaving points off my advancing Wagons (so removing 3x Rokkit Launchers) for a Boarding Plank on the Boss Wagon seems like a viable idea as well.
5) Lastly, and my biggest concern, redundant units seem to be much better than one of anything, and that leads me to Burnas vs Bustas. Tankbustas provide a bit more killing power to MEQ and vehicles, especially when they outflank, but Burnas give me access to Power Weapons (if needed) or A LOT of reliable killing power in the form of templates. I like the idea of running both, but if I need more tank killing power then the Burnas don't see much use. If I end up facing Tyranid or Guard Blobs (or any unit that relies on a cover save rather than armor) then the Burnas would be invaluable. I am considering dropping the Bustas down to 10, and then dropping the Burnas for another unit of 10 Bustas. Otherwise I would leave them as-is and take one of each unit to provide more overall coverage.

Barring the Bustas vs Burnas debate, my personal changes would be:
- 2 Meganobz (80 pts)
- 2 Meks (30 pts)
- 5x Rokkit Launchers, from Wagons (20 pts)

+ 5 Warbikes w/ Nob (PK + BP) (130 pts)

OR:
-2 Meks (30 pts)
-Grot Orderly (5 pts)
Total: 35 pts

+ 10 Grots (35 pts)

The bikes could also provide an alternative for my BikerMek to attach to, in the event that I elect not to Scout up the Wagons, but still allowing my Deffkoptas to move into Rokkit range. I'm just looking for overall thoughts and suggestions. I don't have all the models to run this list, but it does seem like a fun "hammer and anvil" style list that threatens your opponents face and back with scary, killy units up front and terrifying shooting from behind

It is a good idea but there are some things that I would change. I would drop the burna boyz in favor of wagon full of lootas. They can hit flying targets as well as shoot at things on the ground similar to tankbustas but incased in a moving bunker. If you don't go with lootas then another unit of tankbustas would be very usefull.
I would not worry about guard or nid blobs since most people don't play those anymore. Also you could just throw the meganobs at the blob and they will keep the blob busy while you destroy the rest of the army.

I like the idea of a boarding plank for the boss and mega nobs to get off that important charge.

I like the extra warbikes because as you mentioned they give the big mek something to attach to and they can ride with the deffkoptas or split off to grab objectives.

So those are my opinions so hope it helps.

This is taking all of your changes into consideration and I really like this list as well. I could afford to get rid of the Bomb Squigs and trim another 15 pts for a Loota or some extra goodies (like a boarding plank for the Tankbustas in case of emergency). However, the Bomb Squig makes for more reliable shooting on the turn they outflank.
Also had to correct my points on the Shoota Boyz (was paying points for 2 Shootas that were on the Big Shoota Boyz and therefore wasted)
Would you say that the Lootas are more valuable than the Tankbustas? To the point that it would be better to take a full 15 Lootas and drop the Tankbustas down to 10?

 

[R_Squared]

Personally I would leave them as is. The Lootas are ace all rounders, but the bomb squigs pack that extra punch to really wreck face before a charge, invaluable against all super-heavies. 18 str 8 shots, with tank hunter, re-rolling armour penatration, and 3 of those shots hitting on 2+, is just not the sort of capability you want to lose. There is literally no armour in the game that can survive unscathed against tankbustas.

In fact, in an unbound army, I would take as many truck loads of 5 man tankbustas, each with 3 squigs, as I could. Each unit is a disposable armour wrecking machine.

Looks like I need to find some old beat-up tanks (Land Raiders and the sort), because I love this list on paper

 

[morfangdakka]

I like that list as well. Good all around with lots of punch.

 

[Grognik]

Looks like a fun list. I agree with some of the statements above. Burnas are a ton of fun but another unit of Tankbustas is more effective. I'd take them over a unit of Lootas as I find they do everything Lootas do and more while remaining mobile. Lootas are a great option though.

 

[The_One]

The reason Lootas were suggested (that I agreed with) is the sheer number of shots they provide and act as an anti-flyer threat. A unit of Tankbustas shooting 10-15 Rokkits out and whiffing, whereas a unit of 10 Lootas can conceivably put out 20-30 shots while also providing a long range threat. There is only a 1 strength difference between the two, and I feel like Str 7 is more than enough for flyers

True, Lootas do that well and I have definitely had them bring down some flyers. Good unit for sure.

Though consider this, with 10-15 Tankbustas you are more than likely going to get a few hits. They not only have +1 strength but they also have the tank hunter special rule. You are more likely to glance or pen with your tankbustas than Lootas. Plus, their weapons are assault rather than heavy so they can move and shoot. In the end they are a more dynamic unit that gives you more options. I would say that their downside when compared with Lootas isn't necessarily volume of fire, Lootas don't always get 3 shots anyways, but rather range. If you like to sit back and shoot or if you are playing a long range army then by all means take the Lootas.
