I decided since I have a little spare time I'd make another guide and try to help out some more community members. This time I won't be racist and I'll make it helpful to you Hordies too ^^
In this guide I will make a list of the unique items that drop from low level instances. Later I might add on to it with some cool items you can grind for at low levels.
