I had this idea while I ran a vanilla tournament on GameFAQs last year. It'd let you have 5 units in your team instead of 4. Normally it wouldn't be possible to have two teams of 5 units since the sprite limit on a map is 9 (the 10th person to appear on the map would glitch the majority of the time). To prevent this, the idea is to have a "leader sprite", which would be the same on both teams. It wouldn't go past the 9 sprites limit that way (8 generics + 1 unique sprite). Preferably this sprite would look gender neutral, so that players could have either a male or a female without making it look weird when they die. Something like that. I thought I would share this thought before I head to sleep.
