Alright, I'll reveal my way of getting easy weapon skills as a warrior. Basically, what you do is buy +int plate off the ah (It's dirt cheap, trust me) , get to about 250-300+. Then, go find either elemental type mobs, or any other mob immune to bleed effects. Charge in, and spam rend, I got from about 1-365 in less than 10 mins at the lake in winterspring. Some say "Dood just go to SMV and find that totem guy" Well, tried that, took forever, and got ganked twice in the process. I like this a bit better. This could possibly work for any other class that has a bleed like effect, I dunno, my main is a warrior.
Oh yea, I searched, couldn't find anything, and if it was posted, it would be extremely old or something, if It has been recently posted, flame away.
