Disable 3 man parties in All for One

Im so sick of this, I just waited 20 minutes for and afk check because my pc shutdown only to be trolled by 3 guys who picked kench and kept spitting me into the enemy

I didn't flame, I didn't afk, I didn't feed and I didn't disconnect and it makes me upset because for my first offense in 4 months of afk (not even my fault my pc shut down) I get 10 20 minute queues but I know these people won't be punished

They even went as far to admit they were trolling and taunt me saying, "nice try bitch we're in charge" when I picked victor

I'm truly upset that there isn't anything to combat this and I'm even more upset that I waited 20 minutes to be trolled for 25 and I have to wait another 20 just to hope I'll get a fair pick
