This is the only file you need - has all the files included in the other sets.

This has textures for Warchief Armor (all pieces), Vanguard (torso only) and Heroic Imperial (torso only). Not needed if you got v 1.1 (Full Set).

Gives the bottom of the male ranger armor a look like hide. Get this one after the main file and say YES when it asks about overwriting files. Not needed if you got v 1.1 (Full Set)
