The one thing that you really need to know in World of Warcraft PvP mode is that you can be attacked while fighting a monster even. This means that you will have to fight off both the monster and the attacking player as well. One of the best escape tricks that you can use is if you have your own mount. You can get away faster than you would on foot. Of course this doesnât work too well if your enemy also has a mount and they are higher leveled than you!
