The only thing I don't like about this progression system is that it's xp based. This tends to lead to AFK boosters and good grief I've seen wayyyyyyyyyyyy too many of them.
That is true and untrue in the same statement. What we *OG playa* want is separation from the casual players. If we're running solo, due to my ISP I have to, is to have COMPETENT team mates and have good quality games. I definitely believe that there should be separate ranked and social lists for EXACTLY this reason.
JIP effectively kills that though since H2 system was based lots more heavily, 92% wins 8% k/d, on ability to win consistently.
