You mean 4D path finder
I looked into what was planned for GAE and looked into the pathfinder improvements which is based on x, y and t, t = time, so one unit knows where another unit is going and if it can get to its spot before that unit if not it'll find an alternate route if possible, also units in groups will assemble themselves better rather than having one units circle others because its space has been blocked out, always funny to watch. So would need x, y, z and t lol!
Formations could also sort of come under the improved pathfinder as units could maybe find paths in groups if moving together.
