After 3 years of playing LoL
I still have players in my Gold Tier that:
- think Nasus Q is dealing magic damage;
- gank toplane and attack enemy while thier toplaner doesn't have mana and need jungler to hold lane not gank;
- buy Frozen Heart after finishing Cindehulk (gold uneffecient item without buying additional HP) when enemies have fed Veigar;
- not initiate teamfights with 3 tanks (Malph, Amumu, Naut);
- etc.
I know I'm not perfect player too, but for me it took 2 seasons to move from Bronze 5 to Gold. Why THIS kind of players moved to Gold right after seeding if they have no idea about this game.
And add already to your MMR some bonused for knowledge of game .
