I don't object to the rules text of this feat. However, we need to be careful about the precedent of allowing things that are purely player-created and not just a simple twist on something WotC, just because player things are going to possibly interact weirdly with WotC things and cause me to have to ban new WotC things because of this. With Natural Talent, I think we made a feat so airtight that this won't happen, but in 90% of cases, I'm going to have to shoot down new material that is not just a simple twist on a WotC thing for LEB.
I'm not going to vote yes due to that precedent and possible cries of later people of 'unfair' when I vote theirs down, but I won't vote no either.
