Since you guys are genius at this sort of thing, it seems like you could ty in other factors. Things like certain levels of observation experience etc... I mean, maybe to the point that each of those wand locations actually count as a special observation spot for mages (and only post level 30). That way, there is a way to track how many spots a mage has truly looked for...

I can't argue your point though.. I know for me it certainly wouldn't be worth just having a char logged in for hours alone. But then we do have crazy people who spend 20 hours on defenses at level 15... hehe
