To the OP if you only have roughly an hour to play an MMO when do you even expect to be able to hit 50 and run an end game dungeon? Also goodluck being auto grouped if your melee, those classes are extremely aboundant so you will be waiting in qeue regardless you'll have more luck going with an ls group anyways . . . . .

Seriously offline games are more tailored to your play needs and time requirements. MMO's most certainly are not tailored to your available video game time.

I am not trying to be mean I am just constructively answering to your original post and from my experiences as a MMO player.
