chadz, about balancing, does it take into account your KD ratio???
If it does, and it takes the overall Ratio there is a problem: Some players, specially some HA and archer (i know am one) had a pre patch excellent KD ratios. If this KD ratios are taken into cosideration for team balancing, the real statistical balance will be untrue.
If that is the case, I would propose that auto balacing would calculate the KD ration from the player last 7 days, and put that figure into the equation (assuming you keep time based records of players, and not just 1 set of data)
