Yeah prior to 5boxing I was a big proponent of doing collection quests...however, moving up to 5 has shown me the error of my ways. There is no fucking way I'm looting 60 Defias Bandannas when, after clearing a cave and field full of them no less than twice, I only had one set of 5 done. I said "Fuck that" and abandoned all 5, including the complete one so I didn't get ruin my still-matching exp. I completely skipped the bear/constrictor/ravager collections in the draenei lands for the same reasons; though I was masochistic enough to collect Sand Pears on all 5 chars...never again. lol

Thankfully after having lvl'd so many alts and chars I have a good idea on the actual vs database drop rate of things so I can skip the bad ones and do the rest cuz I'm gonna need as many quests as I can get to keep going lol
