Frostwolf is really dead, Mop is the most enjoyable to play if they focus on this cause some point the WOTLK will be removed cause Retail will be released WOTLK, I will be expecting a lot of complaints by the time this happens... It happened Many times before TBC for example.
What is the point? MoP has taken several years just to get the smallest amount of fixes and development. A fresh restart won't change that, and devs/testers keep ****ing up things like classes and raid bosses.
