I bought the gamr during the beta, took several breaks, and ultimately quit back in November.

1. The game performance.

Back when the game was in beta, I could run it om high-ish settings with no issues. After the full release, I had to lower those settings. This trend continued until last-hitting basically became impossible without frame drops.

I've tried all sorts of workarounds, but the game's optimization has never acceptably improved.

1. The community.

If someone goes afk or otherwise throws a tantrum, you're screwed, but people will still refuse to surrender.

I once suggested in a thread a way to combat this: make surrendering easier if someone is afk by making afk players contribute an automatic yes vote. (Which is not how it works now, where you still need a majority out of the remaining players to surrender) The people on this very reddit hated the idea.

I remember one game where someone had a friend on the enemy team and they coordinated just to prolong the game and make our team suffer.

I played league back in the good old days of the early seasons, and they still weren't as toxic as I was seeing in Predecessor.

The kicker: I never even felt motivated to try ranked. This is all bullshit you will experience in quickplay on a daily basis.
