I typically do that, but to be honest I was a little worried it wouldn't refund the trophy, first one and all. ^^'
After looking at the comments I've gotten I think I'll go with the t9 head, it'll be a good oppurtunity to replace that 16 hit gem. :P
I'm actually kind of excited I'll get to have a 4 set bonus for a while, the t8 one was so fun (I beat a Resto Druid in a duel thanks to it!). I mean, yeah I'm stacking the 2-sets cuz that's what everyone says to do, but it's such a shame we don't get to utilize the whole set Blizz made, you know?
Happy!
