The biggest problem I've found personally with Quick chat outside of it being CC match exclusive, is that every single sentence sounds relatively the same, like the noise jingles do not differentiate themselves enough "at a glance" to make it clear what's being said without forcing players to divert their attention to the chat log.

A random noise takes adjustment, because there's no clear indicator of what it even means without having to hear it a couple of times and even then some things end up being used for different reasons making it even more confusing. When you're trying to piece together what you're hearing while your eyes are focused on things like positioning, etc, it can be bit of a disconnect. There's also notably no indicator of goal control outside of a weird blurting noise the goal itself makes, a clear callout would probably sharpen people's response time far better than what is presently available.

Compare and contrast games that have proper vocal system alerts, and it's a clear downgrade in communication. Yes, it doesn't take a long time to look and see what's what, but that little bit of time can sometimes be a crucial difference, and even then it rarely tells you everything you need to know if you're out of position for whatever reason, requiring extra adjustment to figure out what's even going on.

I will grant am pretty used to games like Unreal Tournament by comparison, different genre and style completely, but I feel lessons learned from games like those can help sharpen up PvP in MMOs, at least just a little. It wouldn't even be too drastic a change, or could even just be additive, like an alert if a team is passing a certain threshold with a goal, etc. Could work into other modes too, might even be useful if they ever do a different type of mode.
