So, what do you guys say? PvE or PvP?
In PvP server you can attack anyone at any time after level 15. In PvE you can only attack if you're flagged for pvp, and the other person is flagged as well.
But remember the game has a lot of pvp features, svs, gvg, battlegrounds, duels, etc.
So take your time making this decision. :)
