Ive no faith in SE/Yoshi-P when comes to balancing healers

It's also worth noting that in UwU (the actual hardest content in the game right now) WHM has more clears listed than AST. Almost as if it's stronger thoroughput matters at the very high end.

This is very misleading nowadays. Both Ultimates released before the changes to Malefic III and Collective Unconscious occurred, which caused a sizable upswing in ASTs because they're simply better at both fights than WHM in almost every aspect. People aren't taking WHM for its thoroughput. They take it due to its better MP management since you're expected to die a lot during prog. As for Savage, you have to factor the current clear logs only date back two weeks. When Alphascape was fresh, AST/SCH was decidedly the better healer comp even for prog, and was noticeably favored.

Regardless, the issue people have taken with Vivian is the insistence WHM is perfectly fine and rDPS essentially doesn't matter. To her it may not, but others do care. And it's factually inaccurate to claim WHM isn't the weakest healer in the same sense SAM is the weakest Melee and MCH is inferior to BRD. Presently, WHM is 100% inferior in almost every aspect, which bother many WHM mains who would rather not be repeatedly ask to play something else. It's easy to say no, but if you're looking to broach into the midcore scene or above, you will have a far more difficult time finding a group willing to sacrifice AST so you can play WHM. Of course, this may change come Shadowbringers, however that is the present day meta.

Simply put, no, WHM is not perfectly fine. If nothing changed going into Shadowbringers, you would see a continual deny because they simply cannot match the utility of SCH/AST. They may clear content but a melee comp of MNK/SAM can clear Ultimate. It doesn't mean the BRD isn't complaining every step of the way (or you can't find one, period) because they've been denied Piercing.
