Well i got bored and since soloing with a blood DK isn't that hard i made myself a challenge and tried it with my 70 fire mage....after 2days of practicing i surprisingly made it.

The run was even easier then i thought it took me around 3hours and i've got 130 gold out of it.

i'm testing heroic in the next days even when i think it'll not be possible since the third bosses have pvp trinkets in the heroic version but whatever enjoy.
