An armour-heavy list will eat you alive if you don't get your Stealers into them in a hurry.

Consider dropping EC on on your scutting Stealers. Really expensive and you are going to outflank with them, right? Take those points, and see if you can come up with a second Fex, a Tyrant, some Thropes or something to deal with hard targets at range.

'thropes aren't that great against tanks, so i'm not using them. Maybe swap out the fex for a flyrant.

 

Better to give the Broodlord some feeder tendrils, compared to the rest of the squad.

I don't like hormagaunts, there's basically just bodies. Why go for one hormagaunt, when two spinegaunts can swarm better, altogether, they're going to die horribly. and don't gaunts need synapse anyway? with only one point (The broodlord) you're getting kind of screwed with them.
