Really don't appreciate all the nerfs to The Animatronic's add-ons

Why were so many of his add-ons nerfed in the recent 9.0.2 bugfix? Bonnie's Guitar Strings I can at least understand but the others make no sense to nerf, in my opinion.

But Bonnie's Guitar Strings are just problematic anyway, they shouldn't even be a Rare add-on. I say revert the effects back to the PTB release (no penalty on the undetectable duration), or at least reduce the penalty significantly, and then swap its effects with the Faz-Coin. What the Faz-Coin does right now is so weak in comparison, it does not deserve to be made a Visceral add-on, it should at most be Very Rare, if not Rare.

The reason I think it should be Very Rare at most, but preferably Rare, is because The Huntress gets an add-on (Wooden Fox) that gives her 30 seconds of undetectable when opening a locker. Compared to this, Springtrap only gets 10 seconds when throwing his axe, meaning he must retrieve it before being able to apply the effect again. The Huntress is able to just activate hers with the Wooden Fox by simply opening any locker, with no cooldown.

I could at least understand making it Very Rare however, because Huntress benefits from Undetectable much less, considering she has a Lullaby, whereas Springtrap does not. Her add-on also does not apply a terror radius to anything, whereas Springtrap's does.

With this in mind, if it were so necessary for the effects of Bonnie's Guitar Strings to be of Very Rare rarity at minimum, then I say move Bonnie's Guitar Strings' effects to the Faz-Coin, move the Faz-Coin's effects to the Access panel (or maybe some other Very Rare add-on), and then the effects of the Access Panel/alternate add-on can be moved to Bonnie's Guitar Strings.

And another thing to note is that the add-ons other killers that reveal the progress of generators are of Visceral Quality. On top of this, both of them make use of this effect pretty awkwardly. Wraith must be cloaked, which means he has to uncloak before attacking survivors, and Legion has to be in Feral Frenzy, something they won't have access to 24/7, and when they do, must either multitask while chasing survivors to use the add-on, or waste it just to see the progress of the generators. And both of them still need to travel the distance to the generator they wish to go to.
Springtrap is able to see the progress simply by using his security doors, and is able to teleport directly to each generator in at most 3 seconds by using his power
