Pre-game planning phase.
I'd like to see a change in how the round starts. Instead of starting when there is 1 marine and 1 alien. The round should start when there is 1 marine commander and 1 alien commander.
This allows a sort of debriefing phase or allows some time for some pregame strategies to happen. Having everyone decide on a commander and having the commander let his team prepare for what he's going to do.
Also allows both sides to get a fair playercount before starting. With less people spawning through eggs or infantry portals at the start of the game.
Too often the marines lose because when the game starts, everyone runs out of the marine start thinking someone else is going to command, or someone else is going to build the ip. Then the commander is all alone and generally gets killed trying to protect the ip. And the aliens can easily lose when they don't have anyone to get upgrades.
Just an idea from seeing rocky gamestarts far too often. Open to input.
