Thanks to not being able to de-rank, and the win streak, in the long run less skilled players will end climbing with time. That is translated into a boost causing the more skilled reach Crystal sooner, and late in the season, Platinum players, by average, will be less skilled than early in the season and therefore will be easier to climb.
This is an objective opinion based on how tier ranking system works in other games and how the small changes implemented by SE would affect what we already know. If you are not happy doesn't change the system have been proved by years and years of iteration in other games.
I am pretty sure a Silver player in League of Legends believe too that they should be Challenger rank and they only lose because others, is pretty common but statistics don't lie, on the long run, your skill will turn the balance of your winning rate from 50% to 55% or 45% and that small increase or decrease is what make you climb or getting stuck.
