I just had to dodge my series game because of a troll from last game.
The game prevoius to the one I just dodged there was a mid laner who wanted blue. They had full mana and I had almost none. I told them I was going to take blue and they came over and tried taking it themself. I then smited blue and then the player quit. We ended up winning the game 4v5. I reported the player and then queued up for another game. That same player was queued up on my team for the next game. They said in chat "im just here to ruin your game" then they picked vayne support. I dodged because its more important to me not playing with this person than winning my series but this player has some serious issues and trolling someone like this should be a serious offence. I think a just punishment is that they should not be able to play ranked games for a while.
