How everytime when I meet in arena and my partner burst hum he always swap hp, when it should be forbidden. At first I even didn't know the name of the spell so I looked a bit in internet and saw that this is void shift. Link - > http://wow.gamepedia.com/Void_Shift and as patch log is saying, since 5.3 it shouldnt be use useable in arenas or rated bg's. But ofc in Warmane everyone can use it in arenas.
