League Players Are Worse Now Than They've Ever Been

Like holy shit I've never seen anything like this. I stopped playing this game for awhile, got busy with life and stuff. Decided to pick it back up and grind to 30. I've been playing since Pre-Season 3 so I thought I knew a lot, and I had been keeping up with the changes from time to time so it wasn't like I was going in blind. Then I hit ranked and I've had nothing but massive stomps. What is with these keystones and free damage? Why is everyone playing champs that they shouldn't be playing with? Is this because of Dynamic Que?

I don't understand, I really don't. Back in the day, the average League player was much, MUCH better than this. But definitely not now. Silver in this season is Bronze IV - V in seasons past. I had a platinum Yi in my ranked game, yes, a PLAT Yi, feed his ass off like it was no tomorrow. Everyone is boosted, it's ridiculous. Your rank doesn't matter anymore, not one bit, not until Riot goes back to the way things were when the average League player wasn't a mouth-breathing boosted animal. The worst player decides the game, not the best, the worst.

Then you add in tower first blood and all you're doing is letting the worst player put his entire team behind even more. I've pinged so many times for someone to stop leaving their lane because you do NOT want to give up the first tower. I've pinged, I've begged, and I've pleaded. Doesn't matter, because the average player STILL doesn't care about objectives, or smart rotations, and now the mistakes that people made before that were at least manageable now are NOT, and now EVERYONE suffers. I know I'm on quite a rant now but jesus christ this game just isn't the same anymore. Unless you're D3 or better your rank literally doesn't matter because you're just surrounded by a group of boosted junkies. Let's just all pretend that S6 never existed.
