Not surprised, honestly. With all the magical variety and combo effects compared to melee and finesse's very limited bag of tricks, there's pretty much no incentive (other than the infuriating stat scaling atm) to go str or dex only. At best you'll have a man at arms with a few spells.

Which is a shame. I love spellswords but it's sorta lame that that's pretty much the only way to play other than a pure mage since 80% of all skills are magic...
