The PVP emotes you get are much better to discuss what needs to be done in a fight. You cannot type to randoms about what needs to be done in high action environments. Like in MOBA where pinging is the best way to tell people what is going on, the emotes are a much better way to tell others what is going on.

Too many times the tank and the melee DPS dive well past your max healing range, putting you as a healer in mortal danger because they are retarded. These emote commands are instantly appearing on my bars when the patch comes up, I took one look at them and was happy with the change .
