Hello,
List is pretty cool. I like it; probably a lot of fun to play. Let me suggest a few things though.
What I like about Belial is he doesn't scatter when you deathwing assault. Which means you can be very selective on where you want him. I love the assault cannons on them. A heavy flamer though would destroy a lot of horde stuff though being twin-linked. I feel like your dreadnought is a little out of place, I personally would drop it. Max out your tacs squads. 9 is a odd number to me. Or, drop your
tac sqauds for more termis. Also, you aren't taking
TH/
SS on Belial so you will just have to be careful with him, only toughness 4 without Ethernal Warrior. I would pick up a Librarian and try to fit him some where. The bikes are pretty solid; you can't go wrong with them.
Can't really comment to much on the
BA's because I don't play them but I agree with what
Remtek said. Mephiston is a little overpriced for what he does
imo. Can't go wrong with Baal Preds. Put some dreads in some pods and then you are looking good. Just remember the termis do count for your reserves so you must field enough on the table to be legal.
Thanks and good luck.
