[Gothika]

Well there is reason to max phys, mental and wisdom. But there is no reason to max Magic and Agility. You don't gain anything special from it. Only exp.

Also another idea: (this idea has flaws)
With phys level you can prep weapons..
Well what about with magic level you can prep wands and out int and power on them. But say the max slots you can put on a wand are not as high as a weapon because you will get people with insane ammounts of grace and mana.
