Deathrunes hate me

So its like this. when all my runes turn into deathrunes i get a "Not enough runes" error message..........that's strange...i thought deathrunes could be used as blood,frost or Uh WTFHBRO so its like how do i fix that or am i one of 80 billion death knights that cant use deathrunes for anything......

Four out of Five voices in my head agree.

hmm, i'll give it a try thx
thanks, i was wondering if this was a bug or not during instance runs.
Ya, i got something similar when i changed from frost to blood, both blood runes stayed as death runes. plus with death strike i had only death runes, quite nice but only happened once.
