Do the tantrums stop?

I’m grinding so hard to try and get higher in ranked to rise above the leavers, afkers, feeders etc. but man, it is tough.

Was finally about to crawl out of mid gold and bam, five loses in a row, three of them with quitters/feeders before the 5 minute mark. Spamming good game after one death and then throwing the game.

The other two were similar but later in the game.

I don’t get the mentality, but man it’s hard to enjoy the game when it’s constantly thrown.

My question, if I finally reach plat, does this stop?
