RANKED 5's (Mid-high silver/low gold)

I am going to create a ranked 5's team, I personally will be playing mid lane on the team but all other roles are open. This is a COMPETITIVE team that is going to strive to improve as not only a team, but as individuals. Mechanics, shot calling, everything. PLEASE DO NOT join this team wanting to "fool around" or play casually. This is again, supposed to be for people looking to get GOOD. Post below your main role and the top 3 champions you would plan to play in that role. Below it, please put a secondary role with only 2 champions you would likely play. THANK YOU FOR YOUR TIME!!
