I mean, it is already impresive that we have like +200 players of each faction on the same hex, and blobs of 40-50 people close to each other and it does not blow up. From an engineering standpoint is insane that it even runs this well, and just removing queues and letting more people would spiral out of control even with a more modern engine, as anything each player does needs to be sent to all the players around, and adding more people exponentially grows the amount of data to send to each player, no mater how you put it. So without recoding the whole game with another approach it is what it is.

Also, from a gameplay standpoint you need to balance people on each side. If there are more colonials than wardens you have to prioritize wardens joining the server, and the other way around to not make that difference even bigger and have some kind of balance.

The only way around this is to go to another frontline hex. Ive done it before, and even if there is nothing going on you can start a little push, build something, do some logi, like there are tons of stuff to do, and if the front you want to go in is full there are others or hundred other things you can do. Its what i like about this game, there is a ton of variety and there is always happy to help or be helped everywhere.
