if you look at the quests on a planet each class has about 3, that's not much and if they said its to expensive i call them idiots.
I have played Makeb on a Assassin and Gaurdian and i have ZERO interest in touching it with my alts because i know its going to be 99.9% the same with only a minor amount of dialogue changes.
The next exp could easily add at least 3 or even 2 class missions they dont have to be huge but they would give me a incentive to play through with all my characters, if the next exp is exactly the same as Makeb then i doubt ill continue subbing this game and i doubt ill continue playing it.
Might as well unsubscribe now there is no way they are going to add 24 class missions/stories. Too much cost, too little gain.
