Add More Maps and Permanent Game Modes
We need a variety of maps to play with to spice things up. Although the map rotation is already good during Rank especially when it rotates from Rayquaza, Kyogre, and Groudon.
One important caveat, Rayquaza should need a slight rework with its buff.
Kyogre and Groudon has the best mechanics that doesn't make the game one sided whoever knock out the boss Pokémon.
Make the buffs and effect transferable when knocked out. My suggestion for the effects would be a movement speed increase and attack speed increase by percentage.
If Kyogre is for HP buff, Groudon is for attack buff, Rayquaza should be movement speed and attack speed.
Because even if Rayquaza give high shield, once it is broken down they can no longer score. Rayquaza Theia Sky Ruins need that kind of change.
Aside from Standard and Rank mode. We also want more game modes to play with, it should be a permanent game mode like the Electrode Volleyball, it was once a limited time event, it is now part of the selection.
