I do agree we lack "active" admins. Why not have too many than too few, as long as the people are "good" admins, i don't see it as a problem if there's 1 admin at least most of the times, wich means sometimes 5 admins on at the same time.
Indeed, some people are power hungry, and looses their sense of purpose afterwards. But i also know that you can behave even better as an admin, knowing that the World has it's eyes set on you, ready to label you as a badmin anytime.
On the other hand, EU rageball often has an admin online, wich is good for 30 players, and prevent some intentional delaying from GK (Goal Keeper, ofc, no horses allowed, remember ) and such. Long live Lansamur.
