"Your Rune Tap heals yourself for an additional 10% of the effect and also heals your party for 10% of their maximum health"
Second part doesnt work as it should, it heals party members for 10% of the DKs hp.
And it heals DKs pet too, but not sure if it should do that.

Being a member of your party, it healing the pet is ok I think.

10% of a tank's hp is pretty significant lulz. Probably twice that at least of any caster.
