Current voice limiting options in Wwise are incomplete without adjustable voice cooldown (ie. don't play a new sound of this type unless a certain amount of time has passed.) Voice cooldown is a very handy feature for managing voices, and a default for most other audio middleware.
Furthermore, cooldown for events can be very efficient at managing events that are prone to be posted in quick succession (ie. cull this event if the same event was handled within the given cooldown time), and provides a flexible way for managing sound clutter.
Currently, to implement any type of cooldown, one has to use complex hacks that clutter the actor-mixer hierarchy, or impement a custom solution on the code side. Most other competitors have some type of built-in cooldown feature. Wwise should catch up on this area.
