Hey all..
I don't think this is a repost, because I'm sure this got nerfed in the patch.. But I found another way to do the glowing hands trick =) only works for frost mages tho as far as I know.. because you need an area of effect spell on a pet >.<
k so here's how
Summon you water elemental
Cast any spell at an enemy
while that's casting, cast freeze (don't cast it, but click the button, and let the circle hover)
while your still casting your spell, and have your pets freeze area of effect up on your screen, press any trinket macro (think it only works if the trinket is bound to a key. i.e. you press 6, it casts your PvP trinket)
and there you go! if you did it right, the trinket should bug out, and you'll have glowy hands!
I find this works best with PvP trinkets.
Chou!
