you have to get over the feeling that they are manditory. it took me a while to realise this myself. i grinded my way through golden lotus (revered), klaxxi(revered) and cloud serpent(exalted) before it hit me.
the way i do it now is quite simple; if i don't feel like doing them, i don't. especially golden lotus. klaxxi is pretty fun cause you can do insane amounts of damage (with the right buffs) and they really aren't that repetative with 4 hubs. think i did every one of them maybe 3 or 4 times? thats not too bad seeing i'm 4 or 5k from exalted.
AC and shado-pan are on my "whenever i get the right hub" mode. i like doing things that have multiple purposes. so i only do AC and shado-pan when i get the correct hubs for achievements as well. i finished the achievements at nizuao temple, so if i get that hub, i simply don't do it.
i try and stay away from golden lotus entirly now, the quests are so grindy and so extremely repetative it just isn't fun. i only go there when i have absolutely nothing better to do and with the reputation buff coming on from revered, i might as well hold out. i would definitly like to hit exalted on all factions, but there's still a good year and a half of us in this expansion, plenty of time i'd say.
