Still no trace of the Cass tail update in 7.5, what is going on?

I just did some tests on patch 7.5 and there's still no sign of the supposed Cass tail-update they promoted for in the 7.4 patchnotes. They didn't even acknowledge their mistake when they later modified the notes for the EoN-hotfix. One patch later and still no mention or attempt to implement the missing tail-update for the snakelady.

Right now Cassmains are stuck with a champion who's pretty much been forgotten. This marks the 3rd time where Riot has completely neglected to implement her tail-update, meanwhile it's been on the PBE since over 6 weeks. What the heck is going on?

Any attempt at raising awareness about this extreme oversight simply gets ignored since no one even plays this champion to take any notice of the issue - that's how bad things are. And Riot themselves won't even comment on this.

Cassiopeia hasn't had a single skin in over 4 years, this tail update is the closest thing to a piece of solace and even that gets denied for us.
