It's a bit presumptuous to expect that things will just magically organise themselves for your pleasure, isn't it?
Organisation requires the right of people with the relevant authority, and the time to just sit in and make sure that people are keeping it fun for each other. Blodo did a respectable job of it when the Battle for Oubli was happening, or so I've heard. Without babysitting, of course you're going to get imbalances. That's the nature of people owning ships in both factions, timezones and logging the side they prefer. It will not organise itself for you, you have to work for it. I'd probably suggest Admin or some other kind of supervision for these events in the future so they line up.
