I dont really get the concept of buffing stuff that is already part of an overpowered class

Like why would you buff Cait for example when basically every single adc is broken already except her? Now she is back to op as well, bullies lane, scales into late and abuses mid game.

Or Riot wanting to buff Frozen Heart while tanks are dominating top and jungle and Galio is the best mid laner in the game.. Idk, what about classes that are struggling in general?

Makes about as much sense as buffing Mikaels right now.. Maybe the item itself needs it, but supports dont. At all.
