Don't know if it has already been posted but i found some days ago a funny bug/exploit
First spec as a Dk Runetap, the first talentpoint is enough. But for real ownage take the cooldown reduce talent.
Next Step get the glyph who heals your whole Party.
Now join Wintergrasp or Strand of the Ancients. If you are Leader of the Bg, get all Players who have Tanks atm.
With the bug you can heal the tanks of 10% of their life. If you have some other Dks with runetap and glyph you could do a heal rotation to permaheal the tank eg 1 Tank 4 Dks in group :P
Same thing in Wintergrasp, but much cooler with tenacity you heal the tanks a large amount of health.![]()
