Nicely done description!

Aaah, finally some feedback ! Thanks !
I'm planning on doing Scout and Engineer soundbanks. As for Demoman, Pyro and Soldier, I'll make them if I have some time, but I think they're less interesting. Besides, how will I make a Pyro soundbank ? (actually I'm sure it's possible. I'll see.)

I know people pretty much use the same stuff on youtube, pretty cool.
All characters can be found in link, you might still have to convert though. Personally I think you could improve Spy. (Quality wise)

Ah, dont worry about the sounds themselves, I have this site
http://www.tf2sounds.com/#s=2
in which there are (I think) all of TF2 quotes. As for spy's sound, I noticed they lacked some quality, too. Maybe I should check your link and see if I can get it better.
