It's not as clearcut as it used to be, though. Tauren have a massive effective health boost, but Orcs get Expertise (which is rare as hell, and incredibly good; with an Axe, they effectively get 47 Hit Rating and 20 Dodge Rating; stat-point wise, that's as good as ~100 STA... or 1000 HP, which is as much as a Tauren gets for stat points) plus Stun Resistance.
