Looking for Semi-Serious team

I am a platinum player in the EUW server who is looking to join a team. Can play any position since I don't have main role at the moment but prefer to stick to one position so I can train in the role and get better. I am from London, England and am 19+ years old, prefer team to be 18+ due to experience of maturity issues with younger people. I prefer the team to have high standards in reaching gold+ and are open to criticism (I do not flame or insult someone but if people can't take criticism to improve their game then there will be an issue). I am also very open to criticism. At the moment I am available most of the time until September which is when I start university. Contact me at Gedude for inquiries.
