I know riot wont care about one of their millions of millions players but I just have huge problem. I do not understand why I should be punished when a player is afk. I spent so much time today and yesterday trying to get to silver 2 and after all of that time spent i get to my promos. In my promos my nid afks level 2 after dying to red buff and no matter how good I did bot lane, we lost. Sent me back all the way to 64 lp. And now I have to play another 2 games just to get back to where I was. Im just venting and Im sorry but i always try to keep it positive lately in games but when people do this type of thing its just frustrating. Why can it be if someone afks in game before any objective or significant leads starts you can remake. Its just really frustrating for me to try to climb when I constantly face these types of problems. For most people in that game it was just like 20 lp lost but for me it has set me so far back and my entire effort today was useless because Im further behind than when I started. I know no one will read this or care but thank u if you did
