VCA to control sub group aux level

[eVERB Sound]

Any idea why a VCA would be used to adjust a sub group aux level? Is it not redundant?

I can think of a few reasons.

All subgroups can be grouped together and controlled by a single VCA

You want to hide the subgroups but still have control of them in a VCA layer or layout via a control surface.

You want to have easy access to Mute and Solo controls of the subgroup.

You can get easy access to the subgroup on a control surface by spilling the VCA.

Just to name a few reasons. There are no particular rules to having or not having VCA's. It's merely a matter of preference.
