Pvp where two ppl can attack each other taking turns.
There is a revenge option if you are attacked by someone which would help with the attack, then attack that person back concept.
Also, as murlocfactory said, there is the arena which is also a form of PvP.
i mean 2 people joining a room at the same time. each takes trun to attack each others base. defendeant can also use spells.and offender can can raid. if score of 1:1 it is tie. one has to score 2:0 in order to win..need to wim both defense and offense. only 100 percent count.
