Reasons why the least dynamic aspect (W) left unchanged? #RevertZacUlt

TLDR: Really not understanding why the most unremarkable ability (W), a bland aoe, was left untouched, whereas one of the most fun and dynamic abilities (R) was squashed.

Saddened by most of the Zac changes, mentioned in other posts, the annoying voice, the awkward walking animation, the R.

"The thing is, he uses most of his gooey flair to make his way into a fight, leaving him without anything remarkable to do once he’s there." -This isn't really very true at all. In fact, the blob-soaking mechanic is a mini-game once you're there if ult isn't up. And if it is...it's more than just disruption - it's extra mobility to chase down those annoying Karmas/Lucians/Leblancs.
-But really, you don't have anything remarkable to do when you MISS your E. Which happens. But the new R, in my opinion, punishes missing E much harder since if you missed it, odds are they are able to easily walk out of the new R. -The new R doesn't leave a trail of blobs to continue to use and recharge W with, so it's an incredible nerf.
-Additionally, the reduction in knockup time for E contributes to making the new ult feel terrible.
-And usually, the new R means you're transporting yourself AWAY from your other blobs. If you lifted a carry into your team, ok, but it's still not a great reason to introduce such anti-synergy into the kit of a champion that was fine to begin with. -The new R just feels lousy. I feel the same way about Taliyah W - it's just so unwieldy and awkward to use.
-Btw, his new R has a laugh doesn't follow the lower health = squeaky voice protocol. So that's one positive.

To be clear, I don't particularly have anything against W. Just mentioning it's the boring skill that's mysteriously been left untouched. Even Q was a skillshot before the "update."

The new Q is kinda cute I guess, but I'm so turned off by the ult change that this doesn't convince me to keep playing him. I can't even concentrate on the game because of how much I dislike the new R.

Zac is my absolute favorite champion - I loved his lore, voice (anyone else get a James Spader vibe?), kit, personality, abilities, quotes.. more than ANY other champion. Level 7, high ranked win rate, over 100k mastery points, etc etc. I've told my friend before that I just play Zac to relax because how can you not have fun, even if you're losing, playing someone so goofy? But these changes, especially to his R, make him considerably less fun, meaning I'm probably going to shelve him, which is really unfortunate.
