I was thinking recently of some emotes that I wish were in the game:
/flourish : Perform a very deep bow. Maybe one hand across front and one behind back with one foot forward and one back like Regency or Georgian court.
/balance: One foot slightly out to side with arms out to sides. Imagine a tightrope walker.
/losebalanceforward: You try to keep your balance with your arms flailing but then fall over face first. I was thinking this would be a fun emote when I was in Vaults of Madness the other day.
/losebalanceback: Very similar to /losebalanceforward.
/trustfall: Cross your arms then slowly fall backwards.
/coverears: Cover your ears. That noise is terrible! Use this when there's that one person who is spamming on some skill or when you just don't want to listen.
Some others that might be a little less plausible are:
/cartwheel: Perform a cartwheel. If stationary then the cartwheel is done in position. If while running then you perform cartwheel without losing speed.
/handstand: Perform a handstand. Maybe allow a walk pace forward and backwards.
That's all I have for now. Thank you.
