I also heard that nearly all formulas were wrong, and people were doing twice or more the damage they're supposed to do in raids etc. Also heard a lot of other game mechanics are broken, as well as some events.
Basically i've heard from a few people is that since damage is so high, PVE is incredibly easy and people just blow through instances.
Can anyone confirm? this will determine if I bother playing... also said damage was wrong in pvp too.
