To go to LCS

I am a Silver player that most of the champs abilities and how to beat them, my main go to for mid lane will always be Katarina but I can play other roles like Jungle, Top, ADC and Support, but my preferences are Mid or Support. Jungle as 3rd, 4th ADC and last is top. I like to invade if Im playing a heavy CC Champ like Nautilus, Thresh, Blitz or Pyke when it comes to hooks.
