Trolls are getting nerfed down to 15% haste for beserking come WoD.
Orc's aren't changed much that I can find for WoD.
Goblin's aren't really changing for WoD.
As for crit damage, it's simple. If you do 100,000 critical damage as an non-tauren, you'd do 102,000 damage as a tauren in the same gear. (X * 1.02) X being the damage and 1.02 being 2% more.
