Errrm, thanks for the replies, but I'm a little confused.
There are
thirteen synapse creatures in the list, yet both of you said there's not enough synapse.
I should have added in my notes--those squads will be broken up as needed. (I mentioned this at the end, actually.) The warriors will probably end up being 3 squads (1 hq & 2 elite), the troops will get broken up into 6 squads, and the raveners will probably deploy as three separate squads. I just listed them together for brevity.
The Hive Tyrant doesn't have a Symbiote, I put it on there for laughs at first and forgot to remove them later. I mentioned using Shadow of the Warp only when I was searching for how to spend my last few points--I opted to go with the Warp Field in the end.
But again, I'm really thrown off with the Synapse thing. There's 13 synapse creatures in play here--the winged tyrant, 9 leaping warriors, and 3 zoanthropes (who can move individually). If I've lost all of them, the last thing I'm worried about is Instinctive Behavior.

And incidentally--if I've done my job correctly, every non-Heavy Support unit will be engaged in an assault.
Elzanith: I read your army list before making mine, too--I'm definitely a quantity over quality guy with my forces. My method to deliver the stealers to the line is to pile 64 models in front of then and hug cover. I'm not chasing that silly Turn 1 assault, I'm looking for the guaranteed Turn 2 assault. If I have to charge an IG/Tau force across an open field, yes--I'm screwed. I'm fronting 91 models with one single purpose--assault. Honestly the 'stealers are just my clean-up hitters. Everything else is capable of assaulting from 18-24" out.
Oh, and incidentally, Zoanthropes have Toxic Miasma & Warp Field by default, it's part of their base cost. :lol:
The spinegaunts are a fleshwall to cover my approach. I will gladly sacrifice 160 points to get my stealers, hormies, and raveners into an assault.
