Knights: Disciplined and well-trained in the sense that they went to an academy. Very uniform in style. Typically adorned with well-made armor and weaponry. Usually fights with class, maybe honor. As someone else said, they can be seen as a police force of sorts as well. Employed.
Warriors...
I see your point, but I feel like the 'rough anal-ness' of it can be diluted by just adding an action after it. Some thing like
"Haa... Haa... Haa..." Gasped Gorthorax the Great, as he attempted to catch his breath.
I can absolutely agree with that, it doesn't really sound like it'd be a challenge until you genuinely attempt to apply it. If nothing comes of this thread I'll probably do what you said, since the alternatives are few in number.
