Can we all start to agree Riot match making is crap?

In normal to rank to even flex match making is just beyond crap that places you in a one sided team to play with. Thought Riot would maybe update this pile of tool match making in preseason but I haven't seen a update on that yet.

Also to people who say "Diamond get place with lvl 20 because their mmr is bad in normal since they fool around" is beyond stupid. Yes people fool around in normal but to the point of them having the same MMR as a lvl 20 is just stupid thinking because this Diamond player must be either feeding or just losing on purpose to have a MMR of a lvl 20 no where should a Diamond be even near a player who is not rank 30.
