(A joke from the gods)
You can't expect to implement a PvP system which allows people to kill each other under all circumstances and then punish them to do so.
All the angry guys, let me ask you something. What did you expect form an MMO? No competitive gameplay? No player vs player? Or that the PvP feature is optional?
Then ASK Ankama to dissable Aggro button for non winged players.
Have fun, is a game and people are supposed to fight each other.
Have fun in beating up by same classes over and over cause of "fair and optimized"skills?
Take a chill pill please, pvp always were optional a "show off"thing , even if the endgame when the best gears gathered and max lvl gained there are way much more things to do.
