I downported 3 of the new male Orc skins from the Alpha, they replace 3 of the Mag'har skins for regular Orcs. I decided to replace these because we have playable Mag'har, so the ones on the regular Orcs are easy choices to replace.
To install simply extract the Character folder into your Epsilon directory (where the EpsilonWoW.exe is). I plan to do females as well, maybe the Worgen ones, and DEFINITELY the black Blood Elves when I find their files.
Note: This does not include the tattoos, JUST the skin colours.
