considered separate content and something different when they werent...also KP originally was only bonethrasher we had to wait for the rest.
I'm aware and downed it pre full HH (and afterr obviously). Do you complain about other games having different raid difficulty levels with the same/simillar fights? It was BW's first raid and it was a hell of a lot nicer than some other T1 raids I've done in the past. Soa bugs excluded of course. (And the weird gharj lava touch of death, which was more funny than annoying at the time.)
