You could....

Remove 60 % of the champions right now, and casual gameplay wont even change,

i constantly see the same Champions over and over, what happened to the game that allowed us to actually enjoy a champion for his/her lore and be able to play them and master them to an amazing degree.

Now if you dont pick the champions that are strong as fuck right now... you lose. this game lost so much of its wonderfulness when riot decided to make so many changes....without even caring about the negative impact that it would bring.

(Ex. why would i play Trundle as a Top laner, then the enemy is going to most likely always have a Darius or Fiora who will dompletely smash him) fiora not so much as darius though..

sometimes i open my league client and think.... "why am i going to play? i will just see the same thing over and over"
