Hi,
Facing the current hyper ofensive meta, we can see the walls available right now, are not enough to sustain the damage output in the current pvp scenario.
I believe the release of some pokémons + hidden abilities will help this, therefore I have a few that I consider necessary (feel free to comment yours if you feel the same):
Slowbro/Slowking (regenerator)
Alomomola (Regenerator)
Tangrowth (Regenerator)
Release Sticky web
Heatran (debatable)
I don't wanna get into legendaries, but since we have the 3 dogs, having the 3 birds will allow us to use Zapdos which could also do a great job as a wall.
Kalos and fairy types could also balance the game but, I'm not even dreaming of that right now 😂
I'm not sure if within the PokeMMO engine you can introduce new pokémon to the database without loading ROMs but if we could import some pokémon from future generations, that would be also really nice. In some sort of event, like christmas, dropping some new island with some new pokémon to catch. Alolan introduction, etc.
