It's really sad to see blizzards barely surviving their original reboot. You'll experience double speed and the same distribution of WOW TBC Gold loot, increased boss health, and two times the speed. This recipe is for loot drama and guild collapse. While I'm not a fan of buffs for the world, it's something I'm interested in doing twice as much using the same old techniques. Naxx is two times as long to obtain the same gear , and it isn't any more satisfying since it doesn't have anything like the other ones. AQ is still the same raid as AQ, etc..
The worst part is that the classical era has long been gone. I didn't think it would retain a high population but the cost of cloning characters took out the entire populace. Because no one wants to waste their time, newcomers don't get cheap WOW Classic TBC Gold a chance. It can take a long time to level up, and it's worth the effort if your server is down.
