Ranked Trolls Need Quicker Punishment
Because it's the end of the season, and trolls are coming out of the woodwork to ruin people's ranked games en masses leaver buster should have its parameters for taking action decreased in response, so that trolls will be dealt with sooner and with less leniency . Ranked reports should be increased as well.
Some of the behaviors I experienced last night: Intentionally Afking, intentionally feeding, intentionally abandoning small poke skirmishes letting a teammate die for nothing (multiple games), shouting out teammates locations in all chat, telling enemies where to find the troll so they can kill him in all chat, intentionally baiting teammates to their deaths, fighting with teammates in chat with the intention of tilting them, intentionally stealing first large monster from jungler asking for leash, running down mid sub 20 mins, champion mechanics that allow for trolling were used and usually followed by hehe XD when the troll was successful (since it was LAN jeje XD)
Also a correlation that I've come to notice about these trolls is that most of them are diamond 5 0 LP players, so if you get a person like this in a game of yours seriously consider dodging to save yourself the trouble.
