Archer-
'A thousand arrows may blot out the sun, but one can snuff out a man's life just as easily'
Just as easy as one can blot out the sun with a thousand arrows?
I always liked the quotes from Warcraft II that you heard when clicking on a unit several times in a row. Especially the footmen were quite funny. They would at some point go all pissy about signing up for duty. " 'Join the army' they said... 'See the world' they said..." "I'd rather be sailing." The voice acting was brilliant here as the footman really sounded annoyed finding himself in some remote place where he never expected himself to be. Classic. 
The death knight - or what was the name of this magician unitof the orc that rode a skeleton horse and had his face hidden under a hood - was also awesome. I forgot what he said exectly, but at some point he would go silent upon clicking him, then he would scream "Stop that incessant clicking!" until when he was pushed to far he would say "When my work is finished I'm coming back for you'."
These quotes are probably not very easy to use or usedul for me to post, but I thought I'd share them. 
Since not all races have a moral values that reflect ours, at least a few quotes should be about it being pleasant to deliver pain to enemies and how blood will be drawn to please long forgotten gods and such. The quotes about heroics are still mandatory of course, but there should also be some quotes that some hidious evel being may say.
Here is a mixture of heroic and dark quotes:
"None take these walls whilst we still draw breath!"
"Chances of violence in the near future are rising... Excellent."
"We shall display the heads of our enemies on pikes so all can see what happens to those who defy us."
"Not even the titans shall stand between us and victory."
"We shall stand against the hordes of evil and fight 'till the last man, lest we shall shall see everything we love and hold dear defiled."
"Bow down, mortals! Cower in fear!"
"Sledgehammer, meet some face. Face, this is sledgehammer."
"Tonight, the soil will turn red."
"For what was sone to my family, there is no excuse. May the Gods show them no mercy like they showed no mercy to us."
