Riot tries to be excessively 'clever' with balance changes.
"Kassadin one shots people."
Remove silence.
"He still one shots people."
Remove early poke.
"He still one shots people."
Remove attack speed.
"He still one shots people."
Change riftwalk mechanic.
"He still one shots people."
Gimp slow.
"He still one shots people."
Move damage from his Q to his W.
"He still one shots people."
Nerf early game Q base damage.
"He still one shots people."
Make him an unreliable piece of trash with no utility.
"But he STILL ONE SHOTS PEOPLE! AS in DAMAGE! Nerf THAT!"
Buff's Q early game damage again...
Sigh... This is just one example. But it is a permanent example of how they now balance things. Excessive, drastic changes, that rarely are aimed at the direct problem, and instead keep cycling champion identity and fucking with their utilities.
