I was doing bgs on my lvl 85 frost mage last night that is decked out in blue MoP BoE and crafted gear, at one point I was cornered one of the tunnels at WSG with 5 or 6 enemies against me.

I popped my one-shot macro which actives all my cds at once and managed to kill a pally and a shaman before i died. Forget multi-boxing to feel like a god, just play twinked in the level 80-89 bg bracket!
