New arenas that aren't the simple open circle. Potential arena styles: multiple levels, built in destructible/indestructible cover, PvE elements, enclosed arena (can't be knocked out), destructible floors (exposing holes that players can fall through a la Rocket League Dropshot), shrinking arena (forces players closer to each other). Giving these different arenas unique color schemes would also add to the game's beauty. For example: the destructible floors could be in a volcano, so both the environment and rocks players spawn in would be volcanic rocks. Arenas could be rotated in on a seasonal basis like in StarCraft to change the meta and maintain interest.
