the allocation at provision ranked games

Look the truth is that since the provision has started i have seen many players to fall even 3 or 4 division down by doing 6 and 7 wins . I believe that this is unbalanced and makes all the probaple work of the previous year to goes to nothing. I say all that because i imagine that the same thing will happen to me also and as u have said : Challenger players could lose all ten games and end up in Silver during the 2014 placements, while Bronze players could go on lucky winning sprees and end up in Plat before getting their butts kicked repeatedly until they fell a few tiers. Neither of these are good experiences, so while this year’s placements are still important, they won’t cause established players to swing as far up or down because of good or bad luck. So i don't see that happen unless if i have understood wrong so illuminate me
