Ya I was saying /tell /linkshell for those who love ultra realism with what they call immersion. BuT i personally like /say /shout /party ones at least. (party animation only work if in close proxy to party member.)

Plus these animaions can be used to make movies which helped WoW get those high subs.
Each race and clan can have a different animations also. Which again will add flavor. Maybe give us options to change types between silly serious flirty. Depending on our mood.
