Want some input seeing as no one in the game would back me up on this.

Our support, an Alistar, went 0/8/0 at 20 mins went cloth armor and pots rushed Guardian Angel and then went afk for 2 mins on fountain. I called him a troll and asked other people to report him.

He is a level 30 with a silver 4 ranking. No one else in that game supported me on the report cause he said he was new to the game.
