We are not going to customize the server, it's really easy to unbalance and break the server.
There are clan skills that can increase mana regeneration or even max MP, and many classes have a passive skill that can be enchanted to increase it as well. There is also a few sub skills that can help with mana.
So there are other ways to get more mana without messing up the server.
About geodata in SOD and 7 Signs, should be fixed already, please make a new post and tell us some coords to see where is still having problems.
Best regards.
