Pro should definitely be added imo because it has high team-play when it is a 2x2. Since it's a weapon carryover scheme, cooperation is highly emphasized with the shared weapons. It may seem less strategic with the banana, but pro scheme is best built for cave-like maps so that eliminates the f-6 air support and a lot of the time the banana is used as a strategic tool to keep the opponent thinking about defense as well as offense (i.e. loose worm formation, and single layers of worm placement) and I find it to be more strategic in juxtaposition to intermediate which focuses more offense because weapons don't carry over and players have 45 second turns, 5 ropes for mobility.
