This is a very good system. It's at endgame. You need to enter a queu. 3 specific characters are needed to start a game. Those are 3 big obstacles in front of dummy farmers who try to get these banners by winning against themselves. Let's hope they don't even try

Team ranked is absolutely something that should be implemented, that's where the real competition and fun will be. (if these modes are popular enough of course)

And about the banners;

With all due respect, I think we are tired of seeing the same exact banner in multiple different shapes. I'm sure many would agree that when they heard pvp leaderboards are coming back, we were all expecting some badass banners like the ones from previous pvp leaderboards. I might be the only one who's dissapointed who knows.
I think we should at least have a design on the banner that has something to do with pvp. The old pvp banners are so much better just saying.
