Another Way To Up Your Waepon Skill Very Easily

This is another way to up your weapon skills in a short amount of time and without any difficulty… I dont know if already have been posted, but here it goes anyway. 
It''s very simple… your just need to go in an instance than the level is enough lower than yours. You can do it in group but alone is better for the evolution of your weapon skill. Then you fight mobs with the weapon class you want to up and you don''t die because the mobs in the instance are really lower than your level. I know you will not earn XP from monsters but you will can easily up your weapon skills and also, if you do it alone, you will be able to collect all the money and the items(green and +) because you will be the only one in the instance lol.
For example… A few days ago, I went to do RFK with a character level 48 and my weapon skills reached 220-230/240 really quick and easily. Plus, I collected all the green and higher drops and sold them on the Orgrimmar AH. I made golds and golds, plus the amount of silvers I collected from the mobs in the instance.
What you need to do is to find an instance enough lower level than your level and you go to do it… alone!
…This is my first "real strategy" post and I hope it will be able to help you.
I wish you a good weapon skill grinding !
