Hi All!
Thanks to all for your feedback!
IST is Inquisitorial Storm Trooper.
Thanks for the clarification.
Anyways, the twin-las and heavy bolter pred is interesting. But, all it does is make your opponents target priority easier.
Why do you think that? The target priority wouldn't be easier for the opponent because it is more difficult for him to decide which one is the biggest threat. That's my point of view but probably you will prove me wrong and I miss something.
This pred build has helped me a lot because it gives me the possibilty to engage AV (quite easy) and I'm able to deal with hordes too. Yes he is a bit more expensive as the other combipred.
Melta is how you kill high av backfield units and landraiders as well as any tank you really need dead. Sure they're close range which is why you take them on small suicidal squads like landspeeders and IST's. They force your opponent to deal with them early and give you a reliable way to kill tanks, lascannons just aren't enough. In addition every speeder they shoot at is another unit that is allowing your rhino's to get into position.
Melta is an essential part of how 5th edition is played, with the new vehicle damage chart AP1 is essential if you want to reliably kill tanks.
Hmm.., I agree and disagree. Meltas will help you to open AV very easily. But you need be very near to him and most of the time they will probably don't reach the target because the opponent shoots at first against them i.e. one squadron of 2 MM AB will get a higher target priority for the opponent. I think that I have enough long range AV fire power to pop any LR. This list includes 8 LC's and 6 of them are twin-linked.
If you're going to buy a TLLC pred, either get the sponson lascannons, or leave it with just the turret gun and save yourself the points. If it's heavy bolters you want, there are cheaper ways to get em.
I want both

The problem with the Tri-Las pred is IMO that he is the first casualty and he his very expensive.
Vortex isn't the greatest power to take with a Libby. It is, however, both fun and hilarious, so I say go for it.
I have given him the Vortex because it gives me a Str.10 AP1 small blast which could be helpful against DS-ing Monoliths, Termis or some Nids. But I'm not sure it is worthwhile. Which powers do you suggest?
Are you using combat squads for your Tacticals? If not, they're gonna have a hard time reaching objectives.
It depends form the mission. In KP mission no, in 3+ objectives games probably yes.
However, here is my revised list. The changes are minor one:
HQ:
Librarian
Null zone
Vortex of doom
Probably you will suggest a better power combo here which one will support my list better.
Elite:
Dreadnought with 2x TLAC
Dreadnought with 2x TLAC
5x Sternguard with 2 PC mounted in a Rhino
Troops:
10 Tacticals with LC, PG, Combi-PG and a Razorback with TLLC
10 Tacticals with LC, PG, Combi-MG and a Razorback with TLLC
10 Tacticals with ML, Flamer, Combi-MG and a Razorback with TLLC
Fast Attack:
2x LS Typhoon with HB
1x LS Typhoon with HB
Heavy Support:
Predator with AC and LC sponsons
Predator with TLLC and HB sponsons
5x Devs with 2 PC mounted in a Rhino
Thanks again for reading it and any C&C will be helpful!
