I have known London Calling ever since I began having thoughts of playing tf2 competitively, in fact London was the person who first introduced me to the people I would eventually form my first team with. I think my experience really embodies the type of person London is: he's a nice guy who's always willing to help people out, no matter how new or different they are.
Through the years that I've known London, I've grown to consider him one of my closest friends in TF2, both as a player and as a person. He is almost unrivaled in dedication to this game, he's always reviewing demos in his spare time, watching streams to see what other players are thinking, and practicing dm with his friends. In game he makes calls with a great deal of consideration, and though sometimes he feels flustered, he has the ability to quickly reign himself in and keep the calmness necessary during holds and slow pushes.
Over the last season I have seen London improve so much through personal perseverance and sheer will to improve. Every day he would be in mumble, ready to discuss strats and ask why our previous pushes had failed and how we could avoid it in the future. Without a doubt, he will continue to improve no matter where he ends up. While his movement still isn't the best, he has recently begun to really work on it, practicing strafing almost daily in mge, and thinking critically about his positioning during transitions and pushes.
Best of luck London, here's to hoping that in the future we can once again be on the same team again.
