I wrote a long rant about how I felt about casual ranked players in “League of Legends,” but I wanted to emphasize in this post how much I think they are indirectly toxic for ranked play.
No matter how you want to argue it, ranked mode in LoL should be considered competitive. Regardless of what Elo you are, no matter what division you are in, ranked play is intended to be the “serious” mode for LoL. If you want to dink around, practice, play for fun and whatnot … there are normal games for this purpose.
To approach the ranked mode with anything less than a win-driven attitude is counterproductive and definitely detrimental.
