Yes. I would prefer they expanded on it so that it was actually a further customization of our class/ spec choice that had impact and depth.
Not homogenized, but balanced to a reasonable extent. The current choices for my warrior, priest and hunter are on that path.
If they can in no way, shape or form balance these then sure, pull it. But I pvp as a bm hunter and fury warrior, so the “sub-optimal” thing means less to me since playing my characters “optimally” means going arms or surv. Clicking a button to play something I don’t want to isn’t fun or interesting.
