Why does a 1500kg shaman tauren have the lowest HP in MOP?

Fighting a DK with 690K HP in PVP with 351K HP is hopeless. Where are the days back in 1.x when everyone would run from a shaman? I’ve never seen mages try so hard to get away back then, just one shot.
If this doesn’t improve, I’ll have to stop playing MOP, because it’s getting on my nerves. I’ve been playing Shaman Tauren for 20 years; I love my Shammy. I also play with my DK, but I prefer my shammy.
I paid until the end of the year, no changes, no new one-year contract! Game over, and no more retail.

sounds like you’re fighting a raid geared tank
