trashcan riot matchmaking system

So i have been having a quite frantic and toxic type this season playing ranked due to the crappy matchmaking system created by the master game designs of Riot games. Here are my serious issues i have with this season.

What the hell is this season anyway? Pretty much between lsc players normal and ranked players no one seems to have an idea what this season is really about. You have malz bot, corki mid, the super safe laners top. It seems that this season's patches have been so botch done that now people focus just poke and safe picks. What is going on with the meta? What even is this meta?

why being Gold elo i start bronze 1 on 3v3? Ok main issue. I checked the mmr calculator and 7/10 games win would = silver 1 based on mmr. However you didnt take into account my mmr and i have to start this season from bronze (now mid silver elo). What the hell is that all about?

Finally the true blessing of season 7s wheel of nonsense matchmaking system. Silver 3....matched with BRONZE 5,4's????? really?? Is that what you would call competitive gaming Riot? This season has been a literal breeze of power farming bronze players in silver elo or getting destroyed by players completely out of my skillset. Players who even when you buy certain items in base to show them what to pick they STILL cant buy the item. Certain players who build hp vs resistance piercing champs. How am i meant to progress on a consistent basis if A) im not learning from these crappy players or b) im losing due to poor matchmaking.

Look forward to the severe delay/ 0 response from riot...
