Apparently cloud giants warriors are the race/class of choice for annoying lowbie (level 15-20) griefer characters. They were about 3 years ago (and before) from time to time.
Kill-happy Pincersvirfs seemed to be popular low-mid midbie characters, good for that player who has progressed on from the bash command.
I don't know why people feel cloud's give them the PK edge, probably the resist/flight/inherent damroll and bash. I really wish someone skilled would roll up a level sitting character and just mop the floor with these tools. Problem is, most good players cannot be bothered to waste their time with such pointless pursuits. We need the CF equivalent of Batman - a superhero protecting the weak and innocent noobs against bash-happy giant griefers.
