I'd like to be able to locally use some simple emotes to communicate to the neaby mages.
Examples:
1) Thanks / Positive reply (Pulsating mage)
2) Anger / Negative reply (Red blip blinking like in the ward spell)
3) Joy (Mage swirls around)
4) Sad (Mage decends to ground from levitation)
5) Direction (4 basic directions)

These all could be done in the casting screen or via button on the left side like the slide of the communications in the right side.

This way we could use easy simple communication gestures locally without needing to add friends before or to communicate to the opposing side players that aren't on friends list.
Also this keeps the communication channels a bit off from the yes no thanks bye bye comments flood
