works pretty well in 2v2 arena's.

make sure you're on a voice programme like vent, or the ingame voice chat.

use invisibility at the start when the gate opens, then your friend(works well with a rogue/druid in stealth or a shadowmelded player if alliance) will ping on the minimap where they are, then you just go up and frost nova or any other quick AoE spell to get the first hit.
