The lime green Horde hunter outfit is just as simple as the blue Alliance hunter outfit. The real trick is trying to switch those two colors depending on which faction you are (I've seen a couple blue Horde hunters, but have yet to see a green Alliance hunter).
As for the Darkspear Tabard: I must be blind, I thought it was the only tabard that matched myself and my pet. The generic guild tabard is too white, and the Warsong and Frostwolf tabards aren't the proper shade of black and blue to match my character. What tabard do you suggest? Since I'm wearing the Bear Hide Vest armor, I suppose I could go without a tabard, but it makes me look like a squire rather than the badass I am.
