3v3 and possibly 5v5 in future

Hi I am smallmanbigD I am a big moba player since young age. Haven't played league very long but got silver 3 in promos first time (even though i won 7/10 and was support on most cause I duo qued) but I won't rant about rank system. Anyways I played dota 2 on semi pro level but my team disbanned and have RL friends who want me to play this game and get to gold to prove I know my shit before considering me on team. I'd like to start by finding people preferably silver plus to try out for a 3's team and build a good comp to have starting rank for the season. Name is SmallManBigD feel free add me and talk about forming a team. Thanks and look forward to meeting you.
