I can bring up the Caitlyn VO issue - I'm not sure if we'll be making changes there. However, you're right with Pool Party Graves - it's pretty hard to see on Howling Abyss. We'll see what we can do to improve the visibility. :]

They way they worded that really makes it sound as if they plan to do something with her.
We might see a voice over update. Recently riot started to do those(Lux and Maokai got them) and since Caitlyn is getting a new legendary skin,that likely requires riot to rehire her voice actors anyway,they might update Caits VO again.
Though I doubt there is anything else planned. I mean that post was made over a year ago and we know that Cait isn't even high on the list for a VGU https://boards.na.leagueoflegends.com/en/c/story-art/yghB24Gs-now-urgot-and-eve-will-get-their-long-awaited-vgus-can-we-have-more-info-about-other-candidates?comment=0004
