That's not why wow isn't doing so hot.

It's not doing so hot because its two phases are Facebook games(garrisons) or "raid or die", coupled with an obnoxious grind to unlock flying(which was the final straw for many.

After leveling a few times 1-cap to gets boring as balls. Even in Vanilla I had 1-60 down in 6 days /played so if you knew what you were doing it still didn't take long.
