I haven't played this game in 1 yr. Now that I did..
All I can say is, skill disparity has never been higher. Most of my games feel very one sided in lanes. Two gold players, how is it that one goes 0-6-0 in three minutes with no ganks despite having a favorable match up? How is it that a Diamond player goes 0-7-2 in jungle despite having mastery of said champion and his opponent is a silver ?
I've never seen a disparity between players within the same tier as I have now. I don't mind, I'm not complaining about feeders or losing. I'm just making a statement about my observation. One year ago, if you see two players within the same Division and tier would have similar results. Sure, cases occurred where one fed or trolled but never was it consistent in every game.
I'd wager it's because they changed the ranked team thing. Hell thats why I stopped playing
