So I'm fairly new player but I have been reading a bit and playing on my spare time. I often see the comment here that Boyz can do everything Nobz can. I don't find this to be the case at all, pretty much ever.
I normally have a 7nob squad, PKs Painboyz, cyborgs, armour etc..That squad with a WB is a beast squad and stands toe to toe with most other beefy squads it has faced including Thunder Wolf Calv.
But how many points is this unit worth? How well does it fair against Hammernators?
Also considering that in most of the games I've played I'm facing normally 2 LR's if not 3. In which case 1 nob with a PK in a 20/30 boy squad has a pretty low chance of penning AV14.
How many points are we talking here? At 3000 points and so on, some units are effective that never would be in more 'normal' games of 1500-2000
In terms of the Meganobz yes they are +2 unless they are Vs. PW which everyone has of course, in which case...ooops their dead.
But said PW kill normal Nobz just as fast.
Bikers I haven't experimented with yet, I have been somewhat avoiding it since it seems to be an Ork I WIN staple but I do want to try them.
There is no such thing as an "I WIN" button. Nob Bikers have many weaknesses that balance them, but they are better than normal Nobz thanks to speed and such IMO.
30Boyz + Nob PK = 3PK's, FNP, +4 Armour, +5Invuln at WS 5 (w/banner) ? Obviously it's a point issue but the nobz will toe to toe and destroy many things the Boyz can't.
The biggest thing is, yes Nobz are powerful. But they are relatively fragile for their price. A single Nob with Power Claw can take a few Nob buddies or a TON of Boyz to be his meatshield. In 1500-2000 point games, The cheaper Boyz w/ Nobz option cuts less into your points, allowing you to bring things like Burna's, Lotta's, Trukk's and so on.
Then there is always the volume of attacks to consider. Sure, Boyz can't dish out S8 PW hits, but they can dish out many more S4 attacks per point than any Nob ever could. This can force many failed saves and chew through things like Marines well enough. Likewise, Nobz can fall down to a huge number of attacks like Boyz can, but Boyz are less effected by high power shots (ie Plas/Melta ect.)
Remember that if you wipe out your opponents unit in their turn, your unit is stuck in the open for their shooting phase. The optimal time to take destroying an enemy unit in combat is often two phases. Start during yours, locked during their shooting phase, then finish them off in their combat phase, ready to move again in your turn.
So in summary, Boyz are cheaper, less effected by high powered shots and can dish out a high volume of attacks. Nobz have their place, but it is most effective when they are either Nob Bikers (High speed and resilience) or Meganobz (High resilence and better point efficiency).
