I was on the other team of course. Scariest thing I've ever seen in a game. Is my body ready when I reach Ranked in 5 levels? Have I experienced the fear that is needed to progress? --- It's a good thing I played all that Assassin's Creed
I'd recommend waiting until you have 16 champs and the appropriate runes for those 16 champs (preferably earned through IP) until you jump into a ranked match. Otherwise, you're certain to ruin someone's afternoon, day, or year. --- "One day I'll have a topic reach 500 by pitting a group of gullible fans against one another; and I'll do it with this signature!"
I would recommend at least having 30 champs of varying roles, and be good with most or mostly all of them, also having runes and rune pages for each of the roles, plus some rune pages for your favorite champs.
