Details on the Heavy Clefthoof set changes...
-23 stamina, -12 defense rating, +556 armour.
Makes it a lot more viable once you get out of regular mode 5 mans, as it's the only craftable druid tank gear in the game that's a good thing. In fact this set has just gone from good to flippin' fantastic for me (another 2000 armour will do nicely, thank you very much).
Braxxis also has stamina now so for pure tanking/mitigation it's superior to Earthwarden. Earthwarden is still far far superior for threat generation though so overall may be a better choice for situations where you're not at the limits of your gear.
