Hello, again !
Today i discovered something that just amazed me.
I dominated WSG at level 15 with using just 1 simple item - Mecahnical Greench. You get it from the presents under the tree in Ironforge/Orgrimmar. The greench itself is level 58 mob wich 1 hits every enemy at low levels. The unfortunate thing is that you get only 3 charges and they are limited for 10 minutes each.
Have fun while it lasts and merry christmas !
