Emote I most want....

[Teraniku]

Lillisette's Future Fabulous salute.

[Trisscar]

Ability to shake a ranged weapon at someone would be nice.

[SpankWustler]

A more evocative and expressive /cry emote. Something that involves vomiting or banging one's head on the ground, varying from race to race.

My character needs a better way to cope with the results of the Random Number Generator or the poor little imaginary bro is going to suffer an imaginary psychotic break.

[Theytak]

/sit on a chair/bench, or /lay in my bed. No other emotes deserve the priority of those two simple ones we still don't have

[Avelonia]

/balance emotes

[Kaisha]

All of those canned NPC emotes we don't have access to.

[Trisscar]

Better. Mithra. Emotes.
Enough said.

[Sarick]

You're all beat by this one

/die

same as death animation with emote

Self.
<player> falls to the ground.

Target other.
<player> faints in front of <target>!

The only, issue I see is how will the animation look when we get up. It can't really use the reraise animation. My guess is another animation would be needed.

[Economizer]

A more evocative and expressive /cry emote. Something that involves vomiting or banging one's head on the ground, varying from race to race.

This one is easy, /fume and /angry work well for Tarutaru. Using /toss with an emote indicating a solitary digit also works well. What you need is an emote that has your character shouting something in rage... normally I disapprove of overused canned pictures for this sort of thing but in this case it is very appropriate:

Ideally you'd use a macro for this emote and replace it with a /sh and the name of your favorite person to rage against.
