Megas were handled awfully, but at least they breath some light into older Pokemon. The problem is now that since Megas were implemented so haphazardly, they will have to keep outclassing current Megas with new Megas. By Gen 8, Mega Gengar is going to be UU, and Mega-Fearow is going to be suspect-tested for Ubers.
