What could they be?
Would the active be mobility-based or a damage buff like Blood Fury?
Profession boost passives to skinning or some Orc clan-themed passive buff?
How would Blizzard be able to incorporate all of the orc clans into the racial theme of the race?
Personally, I want to race change my Rogue to a Mag’har to be like one of the Bleeding Hollow orcs. Those guys are badass
