*knowing that this topic was made months ago* ..
I think there is nothing wrong with the level requirements, right now we relatively have a lot of low level users, fewer but still many "medium level" users and a few high level users, the way it should be. Getting a high level should take years of commitment, it shouldn't be something that a stupid kid can go on here and achieve in six months.
Besides, before it took friggin' 120 years to reach the next highest level (29) .. 10 years is nothing you f00l.
