We’re already spawning about 48 units, not counting the ten bots per side, so in total, you’d have 67 AI units if you fill up the bot rosters and have the one player. I know how expensive it is, and we’ve already shaved pretty much everything off the AI, at the moment the minions are just basic pathfinders travelling between nodes and hitting each other. They barely aggro at all. Basically, we’re already doing what you said. It’s too expensive and we need more sophisticated behaviours to fill out later features.
Ideally, I’d like to have an overhead range. Essentially have the AI able to spawn around 100 to 200 units on the map.
