Do you know why you are Iron?
Because you are picking Ryze mid or top and have a 35% win rate with him.
Because you are picking Sej Jungle....
Because you are picking TF Jungle....
Because you are picking Trundle Top...
Because you are picking a champ that in the current META is under 48% win rate AND you suck at them.
Pick something in meta and play a bunch of NORMAL to learn them.
