Champion Diversity?

Recently, I've been noticing my games have become very similar to one another. The same champs are banned, the same champs are played. I want to play what I want and what I feel is fun, but due to different metas and flaming teammates, I feel like I cannot play the way I want to again. These champions are being forced upon me. Ex: The other game I thought, Xerath seems to be a fun champion, I wonder if he is still viable. Within the first 10 minutes of the game, I was 1 3 against a higher ranked Le Blanc in a normal and was already getting cursed out by my jungler. I tried to explain that this was a difficult match-up to which he replied "get gud"- Silver 3 Lee Sin. I felt like after one gank, I was unable to outplay the Le Blanc. There was no item to really help an immobile mid laner against her mobility. I wanted to try and play champions that seemed appealing to me, but due to the current metas forced upon me, I wan't able to have an enjoyable experience. After the game, I told the Le Blanc this and she agreed. She was getting flamed and reported in ranked for playing Karthus. I feel like I have lost that push, that diversity that makes league interesting and new. Different builds and champions just become trampled by the current trend. Trying something new, fun, or even non-meta no longer can be accomplished the same way it used to as all that results is a wasted 20 minutes, a few reports, and very, very upset teammates. I want to play who I want and what I want without knowing I'll be playing against another one of the thunderlords champions. I searched up "champion diversity" on the League of Legends support page to be greeted by "No results". These days of high mobility, assassin carries needs to still allow room for the maybe weaker, but still viable Karthus mages. Although no one may ever read this and ever care, thank you for reading my plea for freedom of the non-meta. -Another Fatigued Mid Laner

P.S. " i would like to write to you, Riot, on why malphite needs to be nerfed. Malphite can build absolutley no armor items and gain up to over 100+ armor. Riot please. Then theres the amount of MR items Vs the amount of MP items. Riot please." -RicePaddyDaddy
