So I am going to go through my match history for the past 20 games and, (discluding premade ones) tally the amount of trolls in the game.
What counts as a troll?
Anyone who intentionally feeds or negatively impacts on the game.
Anyone with such an outrageously bad score, they cannot be playing properly.
Game 1 - 1 (flaming) Intentional Feeder, 1 AFK, 2 players with 0/4 and 0/8
Game 2 - Support 0/8/4
Game 3 - Remake
Game 4 -
Game 5 - Support Followed me around all game to take my cs and annoy me. Then afk'ed after 50 minutes. Top laner went 4/17.
Game 6 - Remake
Game 7 - Premade. Doesn't count
Game 8 - Premade. Doesn't count
Game 9 -
Game 10 - 1/13 Jungle and (flaming) 1/8 support
Game 11 - 0/10 Support + AFK
Game 12 - Remake
Game 13 -
Game 14 - Premade. Doesn't count
Game 15 - Premade. Doesn't count
Game 16 -
Game 17 - 4/14 top and 3/10 jungle
Game 18 - 3/10 jungle
Game 19 - Premade. Doesn't count
Game 20 -
So minusing the ones I deemed as not counting.
5 Games were free of trolls/feeders
5 Had Intentional Trolls
7 Had Feeders to some degree. Intentional or Unintentional (Most overlap with intentional trolls)
3 Were Remakes
5 Were Premades
So playing on my own, and not counting remakes. I played 12 games.
5 of those were troll-free with 7 being not.
Meaning 41% of the games were troll free and 59% were not.
Woo Bronze V
Note: Most of my scores were roughly even. Better without trolls but still not feeding when they were there.
