Lot of the denied/non-negotiable suggestions seem to give the reason "because this is an mmo," but this game doesn't feel any less single player than normal pokemon games. The only thing this game has is the trading economy it seems. Entire game up to the point I'm at has been all single player. All legendary pokemon are gated behind long single-player quests and ingame time. Catching pokemon is done completely solo. The pvp system isn't any different from normal pokemon games except for the switching mechanic, yet certain legendaries will never be allowed for some reasons. By the time you could get halfway to getting a legendary most people would probably have already quit. Some form of team battles should be added for legendary pokemon, or some other group oriented system to really make this game more mmo-like.
Breeding not being in this game is fine, but it's not because the game is an "mmo", it's because it changes the game from a catching game to a breeding game. But even then breeding could be implemented as a once a day or once a week thing. Same goes with the exp share, there isn't any reason tied to being an mmo that this can't be in the game, and it wouldn't make the game easier just less grindy. If y'all want the game to be grindier, then say that, don't say it's because "this is an mmo and we want it to be more challenging."
