I'm not very fond of this idea, what happens if you have to leave due to family reasons and its your 3rd offense? Also you would need a time where it resets because I have left 7 pugs total in warlords and I am not about to get banned for a week for leaving a match where I had real life priorities (which is rare for me). I agree with changing it, by making it so you can not join another pug server and must wait until that pug is over or something along those lines. Should also be for subbing out too. You should not be allowed to sub out so you can go on a different server.
