points scale is simple. i dont know the actual equation or anything. but you get more points beating players with more points than you, and you get less points when beating people with less points. you also accumulate less points over time if you keep beating the same people over and over, even if they have more points than you..
the same is true for losing. if you are high ranked, more than likely not many people are above you with more points. so you will be playing lower ranked people most of the time. so with that said, your losses end up being more detrimental than it would if you were a low rank, since losing to a low rank will destroy your score. you can win 30 matches against average rank players, then all of a sudden someone like valle jumps on for his very first ranked match ever(he has zero points), you lose to him, your rank plummets severely and his skyrockets, and those last 30 wins were for nothing.
win/loss ration does nothing for rank.
pimp willy: honestly, i think quick match is a horrible idea. the game will match you up with anyone, regardless of ping. ill be damned if i get matched up with a 200+ pinger thats super low rank and kills me cuz of massive lag. it would be an awesome option if you could filter out certain ping's. if we were able to do that, i would only use that. but we cant =(
i think im done with ranked matches anyway. ive only legitimately lost 3 times in ranked (one to sirlin, one to bbh, and one to shirts, respectable losses), but im at 10 losses, cuz dropping is still a mess, from beta. im just playing ranked to get my 100 win acheivement and im done =/
good luck getting top rank with the cheating. i can assure you that the #1 guy right now cheated to #1. cuz when you drop on your loss, you get the loss, but you dont lose your points. so droppers points will ONLY go up.
