What role do you play?

gotchu fam. after review you need to keep playing morgana, play zyra, soraka,karma as supports. Rotate them 5 games of soraka till you lose then morg ect. Your second role seems to be top? Stop playing yasuo, stop playing irelia, play trundle,malphite and vlad for toplaners when you get off role. Also work on farming better and stop dying you die wayyyy to much on avg. Oh and stop duoing/dynamic queing.
