A good point here.

You are right,invokers are becoming extinct.I tried an invoker but the thing is they get smashed even by the academy creatures and plus at lower levels ain't got much to do about magic.

I must say orcs too are at a disadvantage.They ain't warriors,they ain't mages.They ain't got hp nor they got mana,They ain't have anything ,not even basic defenses and I say till level 20-25 virtually defenseless.All they got is a big,big,big dex/con/str and nothing to use it for.
