Champion Mastery
Champion Mastery it still does not make me want to go into Team Builder/Normal/Ranked queues and actually makes me want to go there even less than before because now comments will be more along the line of "Well we know what grade you are getting" so on and so forth which makes it more toxic all in all. Also if you have low mastery with a champ while others have high with their own they will see this and go "OMG noob champ" or some such other toxicness
Seriously... this makes my decision to play ARAM and Bots that much more secured
