If you people seriously can't think of what to do with extra skill points, you have no imagination whatsoever. There's ALWAYS a use. Max out Death Blow (if you use weapons). Regenerate? Life Leech? Evade? Potion Efficiency? Hell, even MANA Leech, for anyone using mana? Confusion (combined with Aura projectile enchantments on jewelry)?
Sure, technically you don't NEED those... but they'd be fun to have.
