Normal 5v5 Performance vs Dynamic Ranked 5v5 Performance

Hey all you summoners out there, I've been noticing a very disturbing trend in my match history. Now I know the stigma most elitist Gold+ players have toward ~Gold 5 players, as I am a bronze if you can't already tell form my use of the S4 silver solo queue icon but cast all that aside because I just want some help explaining this as I really think that I have improved not only my attitude, but my performance in general. Anyway enough with the formalities (yes I am still expecting you to treat me and this discussion with respect and the utmost seriousness). I have been winning my normal games rather frequently with an average win rate according to my op.gg profile, but in ranked it is a totally different story. As of the time I posted this I currently have a 50% win rate in Normal 5v5 compared to Ranked where my win rate is 45% but I feel as though most of my wins were only from the enemy having a(n) AFK/troll/feeder rather than winning through my determination and skill as a player. I feel like I only manage to win my ranked games because of either dumb luck or someone else's misfortune, making the win feel like I didn't learn anything (a hollow victory if you will). I'm starting to wonder if I should even play ranked anymore, even though most of my solo queue problems have been fixed. Leave a comment and upvote to help me get filled with determination again.
