I'd never noticed it before now, but I'm okay with it. I mean, I'm not fond of the "spin it around" fluff (which would be both slower and weaker than just stabbing again with your spear). But it makes for a good spear-and-shield fighter, which was a very common historical reality for a reason: It's an excellent fighting style. The game doesn't make it very good without this feat, and this feat in no way makes it broken.This is 100% cheese. Seriously people. Just no.
So what's the problem? The fluff? (I agree with you on that). So change the fluff. Hit 'em with your shield.
