I say no. Whats the main difference between CWA and PVP? There isn't really a huge one aside from the risk. You bind in both, you tank in both, you range in both, you blast in both, its all the same really. A lot of clans use PVP to intimidate lower clans (Ex. I got asked for a fullout pkri by a clan of 70 people, when we have a memberlist of 33) which is pretty pathetic in my opinion. When I say no to requests like that, all I get is "OMG POOR REJECT NOOBS, FAIL CLAN NO PVP."
