IDK. But I posted my autistic response separately... and everything I've experienced lines up with what this post said. Kind of bs to ignore what its saying and just say "AI alert! AI alert!". At least address the contents of what its saying. Just need patience to read more than just 3 sentences

I also have confirmed through extensive amounts of data that there is indeed a factor which will make Bronze players face Plats/Emeralds/Golds and even Master players occasionally. There is always huge differences in my games on my first account which has every item in the game. I barely got to bottom of silver... On my other account with few skins, I instantly shot up to Platinum. The thing I mostly encounter the most is that enemy team will always have another lane that completely destroys our laner and takes over the game. I have faced some of the best players I've ever seen on my Bronze account. Its nice for learning the hardway. Bad for climbing. I can't climb on that just because we are getting consistent bronzes on our team, with full team of golds on their side.

Its almost like...
a Bronze player needs to face plats to get to silver.
But 2nd account doesnt have to face higher ranked players just to raise up a little...
Its not a skill issue... its a matchmaking issue at least enough to focus on it... many people respond with "ignore it" "fight past it" but thats just ignoring the truth, which is vital to objectively improving at life and understanding. Ignoring these issues is just copium with us not being able to understand or control this wildly varying hidden variable. But understanding it, and how to abuse it is just another mechanic in the game. There is a system that can likely be trained, and I've heard about and experimented with it :

Try quitting out and not playing anymore for a few days on an account... every time you get a 5 bronze vs gold/gold/plat/emerald/gold... or an impossible game where you couldnt even learn it was so unbalanced. The game seems to react to keep you playing more... and it will not give those types of matches as often if you can train it with this type of "negative feedback"... its not magic, its just an algorithm.

This system of course leads to people having multiple smurf accounts each... optimally it could be 3-4 people would have just to be able to avoid inflated/deflated accounts.. and people like to have skins when they play... so thats alot of money that Riot wouldnt have made otherwise. Riot never cracks down on smurfing because its half of their money. Makes sense logically, and from experience, and from experiences and knowledge of others.

Oh but on my 2nd new, Platinum account.... I never saw anything besides my own same ranking as I climbed. It was always 5bronze vs 5 bronze... then 5 silvers vs 5 silvers... and then it was 5 golds vs 5 golds...

I've had 2000+ games on each account... but one is Bronze vs Emerald and other is Plats vs Plats as a rule of thumb. All of my friends can't play with me on my Bronze account but on my Platinum account we have a great time. The MMR range between each accounts teams has too large of a delta to ignore.

Its just too bad I don't have skins on my plat account...
