I believe there will be AI ships as well. Cannon fodder really lol. no doubt they’ve tried it with bigger team sizes. I think the issue is likely that once a team has a numerical advantage of two or three then it likely becomes very difficult for the ‘losing’ team to come back and once it becomes 4 or 5 v 1 it quickly depends into ganking and one very unhappy team. 5v5 probably stops that, or at least mitigates it.
