This was supposed to make people laugh, but whatever. -_- Yes mages do need to be nerfed atleast a small amount, two shotting a warrior isn't right.
If I'm not mistaken, Priests and Warlocks can do it too (though I'm sure it's far more difficult with a Priest). It's a simple mishap on Blizzard's part. Apparently, the trinkets were meant to share a cooldown timer (I've heard that, anyway).
Don't worry, Blaze. I'm sure you could still beat my Priest, even without these things. I'm pretty good at dueling, but not when you have an almost endless amount of chances to get the right combination of critical hits (sheep + drink).
In any case, Screenor, I thought it was pretty funny.
