In my opinion reviving should be always an optional traits independently of how good it is the trait. I say that because I hardly revive someone in wvw when there so enemies around and even when there is, they are far enough fighting other people so I can ress without any problem, hence even the minor trait of 5 points is useless for me. The 15 and 25 are so ridiculously bad that I don’t need to argue about.
Anet please change that and give us something good.
