Leaugue of Legends has Updated and my head is aching

Hey guys, yesterday I played some games of League of Legends, its been months since I last played and the experience was really surprising for me. There were a lot of additions like new champions, masteries, meta and no more runes. What did just happened? Even the interface and the ecosystem changed... There are a lot of new skins but those are irrelevant as ever, Riot just wanted money from it, that's all to it. I just wanted to share this cause i felt to... Thank you for listening to my whining.
