I have them in my tos. Made by a small company called fun.com and they somehow put it in the feat tree and named it serpent transmutation to throw off the devs. See when you click it, you don't transmute into a serpent or anything. You just become invulnerable.
lol funny. Sadly, I'm sure there are players out there who wouldn't think you are being sarcastic.
Blame the players. Obviously us players are not playing the PVP content how it was meant to be played. Meaning be a trooper and always fight hard in minis, actually use Bori for PVPing, cant say much for sieging since its still broken, but yall know what I mean.
Devs design PVP content that looks good on paper but rarely works out live because players typically do what is unexpected or not intended. That being the case devs need to improve PVP dev'ing to allow for the human factor. Damn you!
