I don't miss the battling wild pokemon at all, but the shared experience and catching pokemon for exp grind (considering the catch system is so poorly done) is pretty rough. If you aren't using the given Eevee or Pikachu, the game seems to be considerably difficult if you're doing only 1v1 battles. Only getting like 140 exp per pokemon catch at like lvl 32 which is literally nothing.
not to mention if your party isnt full, you have to REPEATEDLY catch and remove the pokemon every single time so they dont absorb some of the shared experience. the interface is poor in doing so and there is no setting to automatically send to the pc (that ive found??)
tldr; its fun, but kind of a disaster
