Nerfing/buffing champs when it's not a champion issue
- Cut her damage because Cinderhulk was too strong.
- Lowered ultimate damage, doubled W cooldown with a halved duration, because it was doing Pure damage and applying how it used to.
- Lowered heal AP ratio because activating more often is broken on a lot of champions with a lot of items
- Increased healing and shield because
doesn't give nearly enough sustain for the fact it's absolutely necessary to purchase.

- Damage lowered because an item that was essential to their kits and increased burst damage was removed.
- Damage lowered and global presence removed because he could block Dragon's autos.
The biggest issue with these changes is that for most cases, they nerf the champion and then delete/nerf the item or game mechanic (Dragon's attacks aren't counted as auto attacks any more) that was making the champ too strong,
THEN FORGET TO REVERT THE CHANGES.
EDIT: Also included (courtesy of Dr Poro):
nerfed, then the other items which were trash were changed to be better.
Lost his killing ability to keep his mobility, then lost his mobility and didn't get his damage or E back, and he still doesn't have his silence.
And who can forget Pentakill Taric?
was nerfed because his early game was too strong between his kit and the Warrior enchant. Immediately afterwards he dropped into the trash can for win rates, to the point he needed buffed later on, but never got changes reverted either.

has a big ass AoE silence that silenced longer and deals a ton more damage than Kass' old silence
and 
a lot lately. Maybe we should give him a break"
