Yeah Nids in KT are at a serious disadvantage. You either take all Genestealers and Spore Mines or you spend half your points on Warriors to get synapse. I'm thinking of taking a single Zoanthrope, but that seems to be a huge liability.
A Lictor and a bunch of genestealers seems pretty fluffy for a kill team game. however, at that point we're just playing space hulk, amirite?!
with 40k its best to get the rules straight then apply imagination and rationalize; you will only get annoyed doing it the other way round
