PLD AoE Idea: Light Burn

[Awful]

I don't think this would really alleviate plds aoe tanking weakness, yes it helps but 10 potency with a ramp up? It has nothing on Drks who have 100 aoe potency ability with salted earth 75 potency ~21 seconds, also added in with Dark Passenger AND has a blind, then you have wars with overpower for 120 potency with full stacks with steel cyclone for 200 potency + vengeance with blood bath as well.

I know it's been beaten with a dead horse but paladins do need tweaking in the AoE department a recent thread talked about an ability from 1.0 (War Drum) that does AoE dmg with huge threat gains that would be something that should be added as it works. Paladin lacks because it only has 2 aoe abilities whereas Drks and warriors have multiple with added dmg that they bring.

Edit: Forgot to add in Abyssal Drain that is 120 potency + heals you for 100% of the dmg dealt which adds even more emnity with the healing threat.
Re:Edit: Forgot to say tank self healing does not :x derp
