when this server was Molten wow, and still new, there was a way to bug talents to give you double. Needless to say, it was very unbalanced. you would literally have shadow disc priest running around literally unkillable, with a gearscore less than 2k while leveling. hunters would one shot any class outside disc shadow priest with so much increased stats and huge burst with explosive aimed and chimera shots.
Locks might not have been able to one shot, but they could infinite loop CC you, if you were anything but a paladin, priest or warrior. it became so much of a problem that the servers went down for about half a day while they hot fixed everything. it honestly wasn't any fun. It was fun if you were hunter or priest and heavily into PVP. outside of that, no.... just no. I never wanna see those things again.
