Event parties

I'm not sure what algorithm you are using for creating the parties for events(I don't mean the small, 5 minutes long ones, I mean the 40 minutes ones), but it's definetly flawed. The problem is, that instead of adding members to a party until the party has 9 members and then create a new one, it instead creates more smaller parties, which really sucks. I've seen 3 parties, with 3 members each, all parties belonging to the same faction, instead of having just one party.

There will be restrictions for parties on events and on maps.
Max party size on event - 6.
Max healers count on event party - 1.
