I would like ;
1 a main quest for the lore of my faction
2; subquest only dedicated to the town/region my character is actually in ( like all town region have theire own stories and eventually consequents depending your action during the quests)
3 some daily quest to keep you awake when you are max level and wait your friends logging and get level max because you just sent them the link to dowload the game (more seriously to get some gold and stuff to up your jobs by example)
4 some specific dungeon/raid quest that only when you finish them, you have access to things that noone else get (if they didnt finisht the same quest)
