First is we should be able to choose what side we want to fight for. It would be fun to fight for evil. Second, balance is the balance of all schools and yet all we got is balance spells and balance type spells that do element damage. What happen to BALANCE OF ALL SCHOOLS? We balance students should get some help in the spirit department.
What do you think Death is? They have strong attacks, traps and blades galore, life-stealing attacks, and high accuracy. It's the school Malistare is from. If you want to play evil, go with that.
Also, Balance needs some new spells, they're pretty weak end-game. I mean, Hydra just doesn't do that much damage. I can easily survive it, while heliphant kills me.
