More quests available for leveling up additional classes?

10 levels in a week doesn't sound particularly fast. I suspect you'd have been faster with a Fate group.

Considering this is my 2nd to last 50 class and that's on top of dailies, relics, and everything else an active 50 player has to do, it's actually great. 1-2 levels a day is a nice leisurely pace, with barely more than an hour of work (not counting DPS queue time, which I use to craft.)

Unlike other games you are not intended to level through quests as your primary source of EXP. You absolutely must leverage your levequests, fates and roulette bonuses to level alternate classes.

Honestly, I don't touch quests unless they give some feature in the game. EXP can be gained much more quickly and efficiently in other ways.
