I want to improve on my support skills and on my league skills in general.

I play League of Legends on the EUNE server and I am a support main. I Have been in a team which was D and on solo my top div was D3. I don't play solo anymore because of school work but I would love to be part of a team for online tournaments or just some fun games with cool people. I have been a shotcaller but I need some practice on **** main champion is thresh but I can play every support there is including some off meta ones if needed. You can check some thresh plays on the link I will be putting at the end of my description but keep in mind they are not high elo games simply because I do not play soloq much.
