Blizzard decided in their wisdom to remove the second M from 1 to 85.
Coupled with ridiculously fast leveling and retch inducing linearity I think it will come back to bite them in the butt. Thee single worst business decision for an MMO long term I can think of IMO.
It's suppose to be a world you can explore as you want, at least it's suppose to give that illusion anyhow. Vanilla had at least 3-4 options to level as you progressed.
And for all you "But you can go back and get "ACHIEVEMENTS" sorry, god mode achievements are not fun in my book, something gained by zero challenge is hardly an "achievement". And leveling speed so bloody fast that it's semi-god mode 1/3 of the way through a zone is no fun either.
