In addition, we're far from consensus on finding this a bad mechanic. Indeed, WOTC says their feedback on it shows a majority like it.
I am voting against it just because my players didn't like it. But, I still don't understand why adding an additional offensive option for that big weapon fighter, instead of replacing the existing one, is the only solution. I really have trouble understanding why someone else playing with an ability you guys dislike takes something away from your enjoyment of the game, as long as you have an option that you do like. What's wrong with more options, to cover different playstyles?
