I have tried to avoid collection quest but I still do some of them - as I ran out of quests in Terrok forrest at 63? and needed 10% more xp so be able to get to level 64 so I could get the quests in Nagrand. Im still in nagran atm. at lvl 65. I've done a couple of collection quests including "I must have them" which sucked.

Im not doing any instances atm. becasue my macros suck and I would have to setup a click macro system and basicially don't wanna spend the time doing it. So questing and enjoying myself blasting away the stuff is an okey way to lvl for me atm.
