I noticed something while playing version 5A, which might be mitigated by this patch's small team damage increases but might still exist so i'm bringing it up anyways.
It seems that the HP decrease for larger teams that was added in v0.0.3 does not apply to your team, but instead to the enemy team. I tested a super simple Eggman combo in 1v1, 3v1, 1v3, and 3v3... 1v1 and 1v3 removed as much healthbar as eachother, where 3v1 and 3v3 did significantly more damage to the enemy and *also* as much as eachother.
