Why in an mmr based system does this wall exist? If you have mmr to move up you should move up when hitting 100, if u have lower mmr you should move down when hitting 0. So why do i have to win 2/3 rigged games at 100 to move up or else drop to 68 lp?!
I mean wtf riot. Before promos i win a game, win another game destroying the enemy so hard they cant take a tower. Then i get to promos with a free win, team cant take a single tower and feeds like crazy clearly outmatched. Next game Garen feeds 2 kills afks and the adc is ragging how they just lost the last 3 rounds and got demoted. Again no tower taken..... I've seen enough of these promos to see that 9 times out of 10 they are far more in the enemy's favor than mine. And why if they are separate games from the 0-100 do they make you go back down to 68lp instead of 100 with a chance to win and retry them? At this point it is clearly obvious they only exist as a wall to slow down climbing in order to force people to play more games. That is poor game design and has nothing to do with an mmr based rank.
So i ask again, Riot, what is the point of these clearly onesided promos in an MMR based ranked system other than a cheap artificially forced wall to slow progressing rank and extend required play time?
