Hopefully turn evil gone for all specs, crusader strike, hammer of wrath and blinding light for holy (or make blinding light instant again). Reduction of the cooldown abilities would also be nice but that is pretty much confirmed.
Would also like to see seal of truth and righteousness merge into one and most importantly for blue rage to return (although im sure this would never happen). I would also like to see Eternal Flame deleted from the game but that probably wont happen either.
