Ranked: People who play it without a Mastery 4 On their Champ
I seriously do NOT understand how people play Ranked with champs they don't even have Mastery 4 on.. I mean that Mastery 5 should be a minimum.
People feed in my game because they thing the champ is Overpowered and they are automatically "gods" with it. At least a Mastery 4 would prove they are comfortable but NO! They choose to use a champ they think is OP but they don't know a single thing about the mechanics of the champion. My heart drops because I know that I will most likely lose the game because of my laner's unfamiliarity.
So if you read this, please play your champ until Mastery 4 and then them out in Ranked.
