AFK in my 5th game of Promo (Bronze-Silver)

Hi guys,

This was the 5th game in my promo from Bronze 1 to Silver 5.

The other 2 games I carried as hard as I could with a great teamfighter - Malphite.

In the last game I was super nice to everyone and told them that it was hopefully my last game in Bronze :)

Fiddle dies 3x, (one time cause he tried to steal red and died) Blamed the death on me.

I didnt curse at him, flame, or talk back - but politely told him that it wasnt my fault that he died for being daring.

Types "I dont want this Malphite to win his promo, see ya!"

AFKs

You can see the difference in the gold chart at the very moment he AFKed.

Cost me silver 5 (temporarily I hope!)

Other than reporting, is there anything I can do?

Is there any advice you can give to me?
