I am very happy with the selection of emotes that are available in the game. But there is one emote that I wish I could use. For me, it would be a way to express gratitude with an emote and not be limited to /hug and /bow, even though I really like those emotes and use them a lot.
But the one emote I would like to be able to share with someone is the ability to "/ShakeHand". That would be a great emote to use and a way to further express gratitude to someone who has helped me with a duty, a Fate or getting some good advice.
