1500pts, Pt 2

Aight, so i posted a first draft of this like a year or something ago. Haven't been 'round in awihle, but I've taken another crack at it:

This army is likely not going to be totally optimal, as it is primarily constructed to represent a short story i kinda have going, but I am trying to make sure it's not explicitly doomed to fail every time. If you're interested, the story can be found here (it's kind of eh): http://www.thedarkcity.net/t3895-fluff-for-force-wip-story

Anyway, the list:

HQ:
Haemunculus Ancient - liq gun, power axe, scissorhand

Baron Sythonax

ELITES:
4 Grots w/ abberation, venom blade & liq gun, raider w/ aethersails and torment grenades [with Haemy]

TROOPS:
15 hellions, w/ helliarch & stunclaw [with the good baron]
15 hellions, w/ helliarch, phantasm launchers, venom blade

FAST ATTACK:
9 reavers, arena champion w/ agonizer, 3 heat lances
9 reavers, arena champion w/ power lance, 3 heatlances

The idea, as might be apparent, is to harrass and whittle down with reavers and hellions, while the haemy and grots smash all they can. aethersails to get there quick, torment grenades to help survival for that next turn.

Thoughts?

Seems really light on Troops for 1500. Stunclaws are overpriced for a gimmick.
