Main supp/mid/jg for ranked games

I'm looking to get a few decent people together for ranked games. I main support; nami, sona, leona, bard, soraka, Janna. Can also play lulu, braum, thresh. Can Jungle; Elise, Hecarim, Rek'sai, Vi, Shyvana. I can also mid with Annie, Azir, Lux, Syndra, Veigar. If you're looking for anyone to play the roles/champs I've mentioned above add me. My summoner name is Wizardlicious. I'm looking for SERIOUS players only. People who can hold their own lanes, know how to pace for ganks, and have above-par game knowledge. If you don't know how every champ works for the most part, then you should probably pass or start reading up on them. Currently I am Silver 3, and I am looking to get to Diamond by the end of the season. EACH season I have climbed by mostly supporting, so that is what I'm best at. The two other roles are what I would prefer to play if not supporting for a CAPABLE adc. But I have champs/runes/masteries for any lane. Again, I'm looking for serious players only. Listen, everybody has a bad game every now and then, personally, as long as you step back and learn, listen, and improve then we'll get along just fine :)
