How does it make it a separate system, in the way of earning points / spending points... hard to explain, like how do i know whento award points to just the class system vs. the all system.
I've actually done this as my guild had a class and cross class list for Blackwing Lair. What I did was make two separate DKP lists, Blackwing Lair Class and Blackwing Lair Cross Class, and I would manually take two snap shots at the beginning and end of each raid (our points were by raid and not kill) and just sort the items as they dropped. It really wasn't that much extra work and it was nice to have them completely separate on the forums. I can tell you that from now on though, we're never going to have two lists...lol...If that helps.
