Witt;
I use the powerfist example because that's your classic high-strength character killer. The Vanilla Commander in question is not going to instant death Imotehk, but he will hit him on a three, and wound him on a two. Imotehk's save is nice but would be a saving grace for this thug-cred only if he had so much as a "rending" option with which to reply.
In all honesty, what's more likely is that the Vanilla Commander and whomever he was with would crumple Imotehk's unit (unless he sprang for Lychguard) and run the Stormlord down as his galaxy crushing logic circuits determine the best thing to do against a superior enemy with a power weapon is to turn one hundred and eighty degrees and walk slowly.
Eldargal, I suppose I misjudged your reaction. Very well then! Each to their own. Personally, I do not at all care for the Damnos webway seizure from which the Necrons launch attacks on nearby worlds. It used to be the Eldar's hidehole, and was en-coolened by the presence of the Dark Kin. Ahriman scratching at the walls made me nervous, but I appreciated his gusto.
Then all of a sudden Necrons are in, staring into my baffled, pointy eared face with their blank robo stare as if to say "oh, didn't you know? We're Older, Better at Tech, and Superior at Predicting things than you. Also, we figured we'd crash on your webway couch for a few nights. Thanks bro."
But I suppose I may simply be hatin'. There's less "Boo Eldar" in this Necron Codex than the Last. And I death or gloried a Monolith for the first time in that inaugural match, so I can't be too mad.
