that was because back than the only "dire orc" texture was bloodboil's. however normal orcs exist already, why would they use fel orcs as placeholders? unless they're planning on creating a new type of corrupted orc.
if they're doing so, I hope it's yellow orcs. I hate yellow and I hate orcs, so it'll be nice to see them together
but please, anything but purple orcs cause purple is my favorite color
