So these are probably my favorite, or 2nd favorite aspect warrior. (Warp spiders take the top spot I think). However in 6th, I don't think I can justify their existence in a list.
Reason: Cannot assault off of the outflank coupled with no effective shooting. Also cannot assault out of a disembark.
These guys usually are infiltrating, behind enemy lines types of assault troops. However with the advent of the new ruleset, these guys have to take it on the chin for a round before doing anything - coupled with the fact that they're typically operating outside the range of a farseer to buff them, its quite difficult seeing how to get these guys to work.
Anyone have any ideas?
