Gragas getting a Buff Reverted and Fiora getting a Nerf Reverted

Gragas: Patch Notes 7.2 Armor increased. Heal on passive increased. Gragas has been struggling to survive his first clear in the post-pre-season jungle; camps with multiple monsters (which he should excel at clearing) proved particularly difficult to handle. Beefing up the Rabble Rouser’s early game enables him to more safely finish his first clears and ramp up through the rest of the game.

ARMOR: 26 ⇒ 29

Current Patch Note: Gragas Base armor lowered from 29.05 to 26.05

Fiora:

Patch Notes 7.14 Passive’s movement speed down. R no longer grants Duelist’s Dance’s movement speed when near the target. Quote.png Playing around Vitals gives Fiora a lot of power, but her opponents are at too much of a disadvantage to stop her from doing so. When Fiora’s striking lone Vitals, the movement speed Duelist’s Dance provides often lets her escape retaliation. When Fiora goes all-in with her ultimate, the movement speed she gets allows her too much leeway to out-maneuver her opponent even before hitting any Vitals at all. In both cases, Fiora’s movement speed rewards need to be toned down so opponents have a fair chance to win the game of footsies.

Passive - Duelist's Dance BONUS MOVEMENT SPEED: 20/30/40/50% ⇒ 15/20/25/30%

Riot clearly doesn't know how to Balance the game since they are going back and forth.
