one of my characters is 100% magic free, and yet has an ever increasing body count. How? Because of a preference of roleplaying combat rather than using mechanics. The magic mechanics are especially bad, for one, a spell never misses. never.
just try and RPing your combat. Not only does it balance the tables, but it is far more enjoyable than just clicking a button.
there's no suspense, no way for you to outthink your opponent, no way to duck and dodge, to parry and counter, no way to use objects in your environment as impromptu weapons, no way to do any of the things that makes combat exciting by using mechanics.
