Back in the day people used to have ships in most factions so when a fight happened they could swap around to balance, that way both parties could have fun and continue having more interactions. Lately it's become the case to just pile on a already weakened group instead of switching, in such cases the other party will just not log to give free blues, these situations were greatly exacerbated during this event where it was 22v9 in some cases.
Only solution is for people to realize this is a small community and the other side won't just get players out of thin air and switch to balance, also not be afraid of dying. It's just a game.
