I mean, I won't lie, most the spells are very powerful, just to be able to burn all your enemies and be at a high level to do so? Just kinda breeze through a lot of the enemies, a spellsword/battle mage is pretty much useless because the spells are what will deal the most damage and with a lot better accuracy than melee stuff. But it's not good for the beginning since you can't get it to the best it could be at that very moment.
also, I only wanted to reply to this, I did kinda wish to be able to just have a Goblin with terrible physical wielding two mithril swords, guess my dreams are dashed away :(
