For Mythic Vectis in Uldir, an adds spawns which must be swapped to and burned when Gestate is cast. It currently only has an audio alert if it is cast on yourself, I would argue that it should be moved to a general alert as it is more important for players to know when it is cast on other players so they can swap to the add ASAP; as opposed to when it is cast on yourself you are incapacitated for 3 seconds and there's really nothing you can do anyways.

I've made a similar request to the BigWigs_Voice mod that was accepted here

Relevant code in BigWigs/Uldir/Vectis.lua

if self:Me(args.destGUID) then
	self:PlaySound(265212, "alert")
	self:Say(265212)
end

Suggesting that the PlaySound() is moved outside of if statement
