I noticed that clans can be split into 2 now. In PW beta 1 you couldn't do a 1 vs 1 against someone of your clan, as to win tons of planets, etc. Now you can, which is much worse than in PW beta 1!
I suggest a balance that balances with clan as first priority (like in beta 1) and then elo as it used to be. The only different thing would be not to start when teams are uneven without calling for a vote where the smaller team can vote.
