In OE4, it would be cool if there was an alternative to boss battles such as a surround battle. A surround battle would be a battle where the player starts with a boss base and is surrounded by all of the other factions. The reward for beating a surround battle is an ultra rare upgrade token (alternative to winning platinum). an upgrade token is a token with an upgrade stored on it which can be used to upgrade 1 unit. (tokens vary)
many ships have lose their purpose once you get to higher levels/players. I think it would be cool if instead of getting a buff, they were to get transformed. I made this comment for no reason considering OE4 is around the corner and cwwallis is done making changes to oe3
