Sorry for not posting, guys, but I've been busy for the past few days trying to get my new computer into a usable condition. I got it yesterday morning and get this, it's broken. I guess it's a factory defect, so there wasn't much I could do. I took it back to the store (drove all the way to Zagreb), where they plugged it in and it was suddenly working. When I got it back home, it worked for an hour, but then the troubles began again. I will probably have to get the GPU replaced, but at this point, it could be anything so I might even have to leave it at the shop. The good news is, I have the warranty so it's all free. The bad news is, I still have to pay for travel expenses so right now I'm regretting not buying it somewhere closer for a bit more money.
As for WoW, here's something. It seems I have mislead you and the cooldown on epic gem transmutes was not removed. Sorry for spreading missinformation.
