I find the Emotes and /dance really stupid and unnecessary when you're out in the field; they can be used for something more beneficial like pre-selected automated voice commands, especially nice for people who don't have a mic, like Up says "I'm going in" Down says "Cover me" Left says "I'm ready" and Right "Not ready" also have a selection of other speeches you can assign the keys to for the user. Another option is quick swaps to other Primary, Secondary, and Heavy Weapons on the fly (ex: swap Sniper Rifle to Fusion Rifle without opening the menu). Any other ideas?
