Getting refused to EX groups as a DRK

[Ipkonfig]

The only time it effects game play is if you let yourself get extremely low and the glitch causes you to drop to zero making Dark Side fall off. Why on earth would you let your MP get so low? At that level of MP you lose almost all utility, you can't grab ranged threat, you can't generate AoE threat, and you can't Dark Arts till you get yourself back to at least 33% MP.

I'm not saying it shouldn't be fixed, but I'm stating it's a completely ridiculous reason to exclude a DRK from content. I've done everything as DRK and WAR and I feel more like a tank on DRK, but it's hard to not play WAR for those sweet Fel Cleaves.
