How to Get Into Non-Empty Lobbies

One last trick would be to do one of the gamemodes that require less players like co-op missions, hvv, showdown etc.

you often kind can't matches in something like ship battles

also, when you que for co-op missions and supremacy you can que for multiple eras which increases full match chances

Getting into a match that can start is often hard specially if you live in an inactive region but make sure that you don't quit immediately when you join a server that doesn't have enough players, maybe someone will join, and you can start.

Pressing the quickmatch button might actually give you empty servers more often than not so avoid using it
