well a good way to stop the use of emotes in fights would be like the perception skill ignorance, or like battlemode whitch shows only the essentials in the fight.

ignorance you can turn on and off so that you dont look directly at runes(obviously), if there could be an off switch, that would be better than an equilibruim drain. so rolplayers can have their fun and fighters wont get pissed off so much.

insteaed it could say something like...

(person) tries to emote but you ignore them. (i apoligise if this example isnt a work of art)
