I recently downloaded an addon to help get "optimised" death strike heals and I noticed my death strikes heal higher than the addon anticipates. So I satrted googling some calculations, and it heals me for about 18% more (75k instead of 64k) than the addon predicts it will. After being puzzled for a while I do something retardedly simple.
I pressed rune tap. With 916515 hp it heals me for 108148 hp. Calculating 7% out of 108148 I get the 75k hp back which death strike heals me for.
So I went to investigate even further. I've checked every buff I had and every passive ability in my spell book, but...I found no healing bonuses.
Am I bugged/being shown false hp/anything, or is this the case for every blood death knight?
