When Megas were first revealed, I couldn't believe they would change such a core aspect of the games by adding an evolution to some pokémon, I thought it was a complete and utter disaster... Now I can't picture the games without them.
I still have some faith in GameFreak, that this ridiculous shit has some purpose and that it will bring some kind of balance, but only time will tell for sure. Also keep in mind we know less than nothing of what this special move does and who gets it.
