Well, if you take the look through bandwitch expenses you shouldnt chat or do whatever is not directly needed to hunt/mine/craft because you overheat servers without making any decay ;o) ... where is the difference between non depositor hunting and depositors sweating/chatting whatsoever?
Huge noob mob hofs are something else even if not all of then are taken by newbies. It is something that maybe gives some hope to new players but take away motivation for everyone else. Another thing is that if you get big hof in forst weeks you dont have to deposit for a long time. So
MA is loosing potentional depositors this way.
