I think it'd be best to save the real work for real life, and leave the current grind the way it is now. I'm all for feeling attached to my characters, but that should be achieved through progression of content rather than being forced to use all of your spare time to gain a single level. Grinding makes combat more dull. Also with the way classes work now, having everything leveled up should only make you feel prouder, since you actually gain something from doing it (cross-class skills).

If I had to spend months getting a single class to 50 I'd probably stop playing. I have a life outside of the game, and I play the game for entertainment. I don't come home from work to get back to work. No offense to you of course, you're entitled to your own opinions and if I had more time to play I'd probably agree with you.
