It's really hard to finish one game PVP, there are always someone who come out and drops the session with a crash.
I suggest to implement a system like :
1° Quit = No penalty
2° Quit = 5 minutes of blocked login
3° Quit = 10 minutes
etc
After 30 minutes of no in session logout, reset of penalty.
Right now it's really frustrating to play, whenever someone quit and reset the round at all!
