For a MMORPG professions are fine.
Better it works, if you combine that with a System, that works in the offtime.
At the time youre online, you can pick out a workpiece or a meal, and at youre offtime this thing would be produced.
The ressources you need can be buyed with gold or were dropped by mobs.
Them could be spend for a quest also.
This works since years in onlinebrowsergames like ogame or Travian.

Combine that two things and PL would be much more of fun like it do in the moment.

Sry for my baaaaaad english....
