Been trying to get out of silver 3 for quite a while now. I don't know, it feels like the community has gone downhill in play style? How have your adventures been going? If you're interested, we could play :D
I feel like you're going to have to get a duo partner to help you out of 'Elo Hell.' For the most part I don't think it exists, but at that rank absolutely it does. Far too many leavers and players who absolutely do not understand the game and it just matters whichever team has more of those to feed.
