Fellow PC player here, I wanted to correct you on something: the PC community isn't really (that) trash, it's just that decent and above players almost never play in rooms, we know each other and always go private with a few exeptions since MK9 really.
what you see are the left overs, and I guarantee it's all true about the win/loss ratio as I too have 2 smurfs (the first one also got too high) to use when nobody from my friend list is online. the wire plug to get no losses is also true, but people do that on PS4 too far as I know.
ps: I added you on Steam, so we can play once in a while, you should add
@RVB too as he does some neat streams for the PC community.
