Zac, Galio, Yorick, Reworks are Awkward and solved nothing.
I really liked both these characters and thought their game play and kit were fun. They just needed a bit of damage/ tank balance. The reworks have completely changed these characters. When I heard riot was going to rework them, my first thought was why? There are other champs that really could use anything to boost their fun factor. I get it. That is my opinion and maybe they were not played that often and wanted to update them to get them back in the pool.
Galio I admit was the most successful of the remakes. His skins are beautiful. His abilities seemed to stray from he was known for. I loved his Ult. When you jump in a group and CC them, it made you feel good. The trade off was longer cooldowns on this abilites and a larger mana use. You had to think about when you were going to use your spells. He wasn't the most technical toon, but you had to think a little. Now his abilities seem like a mish mash of his old stuff that kinda feels ok, but my point is, they completely created a new character. They could have named him anything and no one would have noticed much. I miss his speed boost and shield I could dump on a team mate. He was a true Tank/support character. Now he was built to Top/Jungle/Support/ seen mid too for some reason (didn't go well).
Zac was awesome. I liked bouncing around like a bowl of jello. His Ult is now awkward and I lose him in team battles with it occasionally because hes on the floor. His Q is the most annoying thing in his rework. He seems pretty pointless running around trying to stay attached when his old Q flowed with his old rotation. I don't even want to play him anymore. Sad.
Yorick was a fun remake, but it went away from his ghouls. His abilites that dropped ghouls were a great idea before the remake. I liked they all did different things. They seem like a by product now. Its all about his shovel and his donut of doom. His rework is now lost and was pretty pointless considering you don't really see him much in play. (At least in my lowly cesspool of matches).
I think Galio will stick around for a while, but Zac will end up on the cutting room floor with Yorick with an awkward kit and underpowered when there are so many better choices to lane with.
Amumu, Kalista, Kindred, Mordakaiser, Urgot, Skarner, Zac, Yorick could all use serious attention in my opinion, but don't change them completely. There seems to be a trend to change the characters completely instead of trying to retain what made them great.
I do like the effort. I would rather have a new character then rework an old champion so much, that it doesn't resemble the old character. I think Galio was successful because you created a completely new character and put an old name on it. But we lost the old one. It scares me to think you might remake a character that is great and I love to play and it turns into something that isn't and improvement or isn't the same character (Katarina-Loved old one, New one is clunky. I don't like the dashes everywhere.)
Good Luck on the Rift and feed me. I need all the help I can get.
P.S. I will admit the rework of SION was badly needed and you guys at riot did an amazing job. He was the first toon I ever bought cause I thought he looked cool and if you played the old sion, you know what horror that was. Poor guy. His old kit was lost and you made him a Lumber Jack Legend. Thank You!

....he's been nerfed and ruined enough. If anything revert him back to his original.
