First, remove Mana. The only resource Prot uses is HP. HP now stacks to 10.
Shield of the Righteous: Now costs 4 HP
Flash of light: costs 5 HP
Crusader Strike: increase damage to 150% weapon, and generates 2 HP
The only Ret spell i looked at
Inquisition: Now works similar to Word of Glory. Can use anywhere from 1 to 5 HP, each HP used adds 10 seconds to the duration. Using inquisition while its already active with add the new duration to the existing duration (using a 4HP inquisition with 13 seconds left will apply a new buff lasting 53 seconds).
I got lazy and didn't recost everything, that's as far as i got.
Guarded by Light: now also increases hit by 4.5% and expertise by 7.5%
Sanctity of Battle: Abilities no longer benefit from haste. Parrying an attack increases haste by 10% for 10 seconds. And dodging an attack has a 25% chance to reset the cooldown on Judgement and cause the next Judgement to not trigger a cooldown.
Holy Wrath: does 400% more damage when hitting 3 or more targets.
All seals are off the gcd and now will consume 2 HP if available for an added effect (can still switch without the HP, just with out the bonus effect). Using HP on a seal will incure a 1 min cooldown on the seal.
Seal of Truth: Activating the seal applies 5 stacks of censure to your current target, and for the next 10 seconds Judgement will do instant damage equal to 15 seconds of censure.
Seal of Righteousness: Activating the seal deals 30% weapon damage to all targets within melee range, and for 10 seconds after Judgement will hit 3 targets.
Seal of Insight: Activation the seal heals the paladin for 10% of their max health, and for 10 seconds after Judgement will heal for 5% max health.
Feel free do dissect and criticize me ideas, and add your own.
