Dunno how people understand this suggestion, I dont. Maybe its something with me.
He means that raw k/d will only be counted relative to the scoring system we have now.
People won't be able to farm k/d as civilians or armor whoring, hence you see those typical responses above.
Their stats would be relative to their gameplay in PTP. Obviously some people won't like this because their precious ratios will go down. Because the only reason they have any ratio above 1:00 is by stealkilling as civilians or other forms of k/d farming with minimal effort.
But I am sure the actual pro players can still remain strong without it. Unless all of them were all farm and no skills.
