Advice now that Zolo is 'fixed'

[Toned]

Exploiting something doesn't mean you're doing something wrong. Ever buy low sell high? Thats an exploit. Do quests in a planned order to level quickly? Exploit. Save quests to do after you hit 70 for the gold reward? Exploit. Level up and do a group quest by yourself at a higher level than intended?(or play a hunter) Exploit. Play multiple characters at the same time? Exploit. In all of these situations you're exploiting a game mechanic that is intended, but the results of someone finding a way to get the most out of it probably wasn't intended. They knew you could sit at zolo spawning stuff that gave exp, they just didn't think it could be so rewarding.

And it wasn't around before TBC. You needed level 70 to make it work to a degree worth using.

I think you're confused about what exploiting is. Saving quests or doing them in a planned order isn't exploiting. Working the auction house isn't exploiting either that is taking advantage of some one elses stupidity. Sitting at Zolo doing nothing is exploiting, opening the mechanar chest as a rogue was exploiting the mobs pathing.
