Honestly, this change needs to happen for purely non-cheese reasons. For example, if I have a character that is actively hiding, and the rest of my party gets spotted, my hiding character does not get to roll initiative. Instead, they are out of combat. If the enemy team is going first, this can be devastating because the enemy can all go before my party. The entire party, if in the same area, needs to get initiative together.
This is a good point. I hadn't thought about that. This scenario has happened a number of times as well, actually. All the enemies go first and kill the single character while I'm trying to get even 1 more character into combat range to join. It sucks in reverse when the enemies all act before that 1 character and because no others are engaged in combat, they all gang up on the one.
