I think the chainsword is just too much better over a regular knife/sword/cc weapon, and its just a cool concept. so i was thinking along the lines of allowing to reroll failed to wounds or decrease armour save by 1, or maybe both. it makes sense fluff wise as the chainfist doubles against armor, so a chainsword should be better against chewing through armor or similar, while the many teeth make it hard for something hit by it to not get maimed, so the reroll would make sense too.

pts wise i think 2 pts if its one or the other and 5 if its both.

what do yal think?
