|There's more than one way to do things|
New levels? Yes, that discussion comes here from time to time; a long ago I started one myself, just for fun.
Now, for what concerns myself, it took one year and a half to become a Saint, and it seems a reasonable time to me. And those that made it faster look like they deserved it, so I don't see the need to add more levels.
But if there is something that I would change in the system, is the opportunity to gain points without having contributed even a node to the monastery. If it is important to encourage people to vote so that good nodes get a good reputation, isn't it as much important (as least) to encourage people to write good nodes?
So why don't make the probability of gaining XP points by voting other's nodes proportional (someway) to the number of nodes posted? Something like:
p = P * f(N,XP)
where P is our current probability function of gaining XP points when voting a node, and f is a function of the number of nodes posted N and the experience gained, so that f(0,XP) = 0
My few cents...
In theory, there is no difference between theory and practice. In practice, there is.
