I would assume that they focus on this a bit less because a number of people communicate with other players through Discord, Steam Chat, or such as myself in person. It kind of makes the communication systems redundant (in my opinion).
What I would love to have though is a limited number of Emotes, including things like dancing. There doesn't really need to be a specific reason to be able to emote, but for me just being able to make my friends laugh with an unexpected dance on the 5th turn of a fight, is precious.
