Who cares about balance, this is not a MMORPG, just play with no items and hardcore mode or something.
I want rule the world as a wizard god.
Even mmos got DESTROYED by ""balance"" cultists. Look to 90s mmos. Ultima Online, Dark Sun Online : Crimson Sands, an mmorpg with you ROLLING ATTRIBUTES, etc; and look to modern mmos, are all about managing cooldowns and farming stat stickie carnavalesque gear in a world with zero character individuality. Balance is good but not above role playing, fun, rule of cool, variety and etc.
Wanna make the game 100% balanced? You now can only be human ranger at lv 8 and will be a human ranger at lv 8 for all the game. No imbalance among player choice. Fun? No.
