I also think that there shouldn't be a waiting time for planets. Maybe multiple squads could join at a time and attack and to win you have to take all the bases. Then you were warped to the waiting room where you could instantly attack again.

VIP spar should be gotten rid of because I've never even seen someone in there.

Last, the Pk arena shouldn't be deleted because it holds Rambo. And when theres lots of people in, it gets really fun.

Most of those ideas are good
