There are no bonus Stamina talents. Prot paladins get +10% Stamina at level 10 for choosing Prot spec. We also cut the Spiritual Attunement mechanic and the "Improved Divine Plea" mechanic. Instead, Prot gets Judgement of the Wise (sans the raid Replenishment effect) as a passive, just like Ret. In essence, the melee paladins should rarely run out of mana, and if they do, they always have Divine Plea for emergencies.
Mana will still matter to them in the sense that if a Ret or Prot tries to be a healer or spam Consecrate, they'll blow through their bar more quickly than it will refill. But if they are using their normal attacks, mana should stay in a steady state.
(Note that Prot can still use Consecrate without spamming it by taking the long duration talent.)
