PvP would be fun if, players wouldn't suck so bad. Worst PvP players i've seen in an mmorpg, are here. Please go back to your holes and leave PvP for the players that have a brain to do it and go back to killing NPC, cuz that's all you can do.
True that ^ Look at stealth in WoW. You are permanently invisible, but it still works. Thats why its called a Rogue, so you can stealth how much time you want unless, you attack, being attacked, or you got hit by an AoE.
