Love how no one is talking about Vi getting completely gutted in 9.3

Ahh, I see you've written quite a lot on the topic. Much work was put in here. I will reply with a comment explaining why she's not getting gutted, just shifting power around with the same eloquence that you have written your post with:

ahem

She's fine.

Define "gutted"

She is now a crit ADC. Deal with it.

How is she being gutted? It's a buff. Q is changing from Bonus AD to TOTAL AD. Damage numbers should be similar.
