1st thing- you got the Tervi points wrong- your list is 1510 points.
now lats go 1 by 1:
HQ- HT need to be specialized Either shooting or CC- either dual dev or dual St. plus- TG is batter then Shell- 2 more wounds and cover(as the HT will not count as MC anymore)!, why is the hive commander? you don't need it! scrap that:
Hive Tyrant Brood (265 pts.)
Hive Tyrant (1) - Twin-Linked Devourer - Brainleech Worms, Twin-Linked Devourer - Brainleech Worms, Paroxysm, Leech Essence = 200 pts.
Tyrant Guard (1) - Lash Whip = 65 pts.
Elite- you really need more AT- at least 2 broods of 2 HG, so:
Hive Guard Brood (3) = 150 pts.
Hive Guard Brood (3) = 150 pts.
Troops: 3 warriors aren't going to do anything, they lack bodies for CC and lack the guns for shooting. scrap them.
the Tervi doesn't need ST- waste of 5points, and even after that he should cost 195.
Terma- no comment
Stealers- 10 is a bit over kill most of the time, I'd say reduce them to 8 if we'll need the points. so:
Tervigon (1) - Cluster Spines, AG, Toxin Sacs, Cat = 195 pts.
Genestealer Brood (10) - Toxin Sacs = 170 pts.
Termagant Brood (20) - Fleshborer = 100 pts.
Fast Attack:
Gargoyles- no comment, but you need to move them carfully so they wont be out of synapse.
revaners- same as warriors, at least 5. scrap them. so:
Gargoyle Brood (20) - AG, Toxin Sacs = 160 pts.
Heavy Support:
Tyrrano is a solid choice, I like him. but at that point level, he doasn't need Reg. note yourself- most people like 3 Zoans in a spore batter and they are 30 or so point cheaper.
I still like the giant cannon Idea batter, so:
Tyrannofex (1) - Rupture Cannon, Cluster Spines, Thorax Swarm - Desicctor Larvae = 265 pts.
we still got 45 points left, so we'll take 1 Terma out and bring in a Broodlord.
so overall:
== HQ ==
