I can understand where you're coming from when it comes to the descriptiveness of emotes, I myself can't type extremely fast and often find myself having to shorten down my emotes or being left in the dust. MOST of the characters I played before I came to ARR were broody, in fact, almost all of them and there was one thing I hated about playing them. With a quiet broody character, unfortunately, more emotive description is necessary unless you want to keep repeating your short phrases (emotes) over and over again. Now as a player of broody characters before I understand that and don't mind either waiting or seeing repeats but my personal experience with broody characters is that unless they're sarcastic and somewhat outspoken their little body languages are important.
A simple quirking of a brow or tick in their cheek is all they have to communicate unless they're a yeller and prone to outbursts so those little emotes are important if you want people to know what's going on with the scene in your head. If you don't give them that information they may have no idea that your character is getting angry or that they're even interested in what's going on in the conversation or scene. Now I could be a complete oddball here and the opposite of everyone but this is just my personal experience, broody characters are great fun but they take a little more effort to play sometimes, to add a some ease you can always give your character a temper or something to that effect.
