The best proof that the game has too much damage and that runes broke it
Here is the ultimate proof of it : one shoting multiple opponents with one r karthus only and getting 3 levels ahead...
The koreans that began this new way of playing and boosting have something close to 100% win rate...
This shouldn't be possible.
Even if you like it this new rune system and new items plus towers nerfs those made this game more unbalanced than ever...
