User blog comment:Leyrann/Placement Matches - The toxic that creates the Elo Hell feeling/@comment-62.226.32.45-20121128130727

the problem with your k/d/a-solution is clear: If you want it, then you have to find a whole NEW system. elo is a rating-system that is based on clear win/loss situations, variables like kills/assists/deaths are not easily introduced into the system as it is simply not MADE for these kinds of equations.

for the placement match removal I kind of agree, the problem is that this would HEAVILY favor long-time-players that made their start in that system (as in starting ranked, being placed about 1700, then going up to 2k+). climbing up from 1000 after placement to like 2000 may take approx 2k games with your assumption, but climbing up from 1200 elo without placement to 2000 (where you may or may not belong) would just cut that down by about 400 games. thus, new ranked-players would have a nigh unreachable target of having 2k+. A hard reset of ALL players' elo would be needed then, which would in turn hurt many many more old players than it would benefit new ones.
