Oh... this would turn certain Pokemon, especially ones with a wide movepool to become even more dangerous. (Mew, Arceus, Mewtwo, Smeargle, etc come to mind.)
Pokemon will have to pretty much reboot everything if this happens, so no, I would not welcome the change very well.
exactly what i thought. smeargle and mew would become especially overpowered. it would completely unbalance the games.
