Does WWE need heel commentators again?

Initially, wrestling always generally had commentary teams consisting of a face and a heel, and it should go back to being that way. The heel always provided entertainment during matches, especially dull ones. The last thing we had that was the closest to a trule heel announcer was JBL. Striker is a great announcer, but I wish they'd turn him full heel since I think it would get us through some of ECW's dull matches.
