Automated Tournaments, Arena Online (RP, Prizes, Scholar ships, etc.)
Arena Online is an automated tournament system, that matchs you with players of your current skill level (You must be ranked in Season 6) It is currently in Beta and runs on Fridays, Saturdays in Sundays while its in beta.
Its only one click and you just wait in queue to get into a game. Currently it kind of acts like "Solo Queue", where it just matchs you up with players of your skill level, no need to look for 4 other friends. But I do believe they are working on making Tourneys where you can group up with teams of your own!
Sign up here: https://play.arenaonline.com/login/create?referrerId=9V1RBmRlV (My referral link :3) And Simply click "Launch Arena Online" once you make an account and join one of the queues if its open.
You can win RP, Cash, College Scholarships, prizes, etc. And the websites special "QP" points which are used to rank players and the players with the top amount of QP points get a bi-weekly prize!
