This happen because the host which is not playstation but the actual developers for the game is losing and they don't want their ranking to go down...F****** losers. They also have ways to power up faster than the real players so they can get more kills. They could go suck a **bleep** cheating **bleep**.
I bought the game with intentions of pure online fighting. I have completed multiple characters trials and Arcade modes, only as a means as something to do while I hope the servers come back or something. I have joined and been disconnected from over 30 matches in a row. It isn't my internet so I am assuming it is other people, but is it really possible I have had so many back to back people rage quitting?
