Why so many AFK/Griefers?

Im struggling a lot to play this game solo these days. Its the most frustrating experience ever. I legit think every third game I have teammates that are either: - AFK - Leave the game early (like 30 Seconds in) - Griefing (just driving around doing flips)

I cant leave the game because That gives me a 5 min penalty.

If I stay I have to endure playing 2v3 and almost always loosing.

When the game is completed I derank. Its especially stupid when I derank after a m8 leaves after max 1 min. What am I supposed to Do? I feel like its very harsh to derank when you play 2v3.

Ex: today I deranked twice, both games I had people leave the game and 2 games I had people trolling. 3 games Where legit.

The funny part is, i re-que and get the same dude I just reported and blocked like 2-3 games in a row in my team.

Anyone else or just me?
