If I recall, some of those classes got proper changes very long after 2.0 came out, that's unacceptable and they should have learned from that.

It's SE own fault for not doing proper PTR testing with the classes, they should have a system in place for this. (And I say for the classes, nothing else that might spoil content!)

The OP says he's been asked to leave content for playing a class he took awhile to level, perhaps he has no time to level another class and thus it ruins his enjoyment of the game, which he's paying monthly for I might add.

As for the team listening.. what? Yoshi-P made one statement ON THE JAPANESE FORUM, that's been translated half-arsed or Yoshi-P made a skeptical comment on how the classes 'might' be broken at the moment and how the 'might' fix it in some manner, of course he's not telling us how.
