if any of you have read the 5th edition tyranid codex, you will know that the swarmlord has a rule called "blade parry", which is essentially "dodge". i just think it's odd that drazhar doesn't have that.
(this might be threadomancy. i didn't see anything about this specific topic so i'm going to assume it's OK. please PM me if i'm wrong.)
Death?! You want death?! I'm afraid that would be far too boring.
