ntrudr is a long time Warbirds player.
For those who arnt aware, Warbirds in a desperate attempt to seem populated and alive, introduce AI into the arena - both flying drones and some gv formations that attack fields. These AI show in the server list as players online.
Ntrudr, there are no AI in the arenas. Whatever number you see in the lobby for each arena are actual players. As you log into a server, little by little the players 'draw' into the list. A 400 player arena will show 52/34/44, for example. Hit the refresh button after a few seconds, or continually click it to see the numbers climb.
There is no shenanigans here - what you see is what you get, give or take the constant coming or going of players in real time.
Hope this helps,
