Maybe you make here very slow exp like x2 and pvp enforced without skulls + infinite runes , or runes style outcast server where you can create mana runes all runes x25 or x100 to use.
But on roogkard make faster exp than x2 maybe x 15.
What do you think about this solution?
I remember that there was once a rpg server with infinite runes and it was pretty cool, or Dark ots servers where people have runes with many charges.
Then there more fights , and people for a long period of time would not drive a big lvls, the server could have stay online longer, because when people see that there are no high lvls they are more likely to join the server.
