I have seen the new PvP chat "emotes" and thought about how to use them without filling your hotbars with unnecessary actions. I found Smites Voice Guided System (VGS) to be a great idea.

The way it works is that you press a key to activate the "System" and are presented with an overlay displaying all your command options. You then press the key associated with that action and the message is broadcasted (translated like the auto-translate feature) to all players from your team. The voice output would be a great touch but I would even enjoy it chat only
