While this doesn't help in the slightest, just think of all the games you won because of afks, it helps me calm down a bit at least.
If people AFK.... sure it happens, not much I can do about it. It's when they AFK during my promos that it angers me the most. Sure I get wins when my opponents AFK, but who cares if they don't do it during my promotion games. Seems to happen so much that it almost seemed staged by Riot.
"Oh, 2 people in a promotion game.....hmmm, lets disconnect one of them, so that individual is guaranteed to play a little longer in that tier".
If you get the wins, you deserve the promotion through the ranks. However if you want to advance to the next tier, than it makes sense to have promotion games to feel that accomplishment. This really has me not playing ranked option, feels like I am jumping through so many hoops, when a ton of them are out of my control.
People say to carry, however I am a supp main. I do very good as a supp as well. However if other lanes lose..... not a whole lot I can do aside from stun people for my team, and soak damage.
Just hope Riot looks at this for the upcoming season. With the new Master tier, something needs to change.
