Welcome back! I think quests have been made to be a lot less tedious, I just sporadically quest now and then for a little income, sell that when I get a chance to price my shop, but mostly I spend time working on achievements/pets, that kind of thing :)
Since quests have been reduced to 15 for GA, it's actually pretty manageable compared with the older 30.
Feel free to ask if you have any other questions~
