If you said normal Rag, I would understand that.. but they're on heroic.. Is it normal for any guilds to beat the content within 1 month? less then 1 month? We're not even into 2 weeks of a new patch and you're going to have the content beat already.. Was there any guild that beat content in 2 weeks, within 1 month during vanilla wow? BC? WoTLK?
Guilds that spent a lot of time on the PTR are the ones downing all the normals so quickly and getting onto heroics. The majority of guilds did not spend hours and hours practicing the new bosses so they could be the first ones to down them. From what I've seen, most guilds are between 2-4 bosses on normal at the moment.
