Again as i said you simply dont see or simply dont want to see the bigger picture. Its what you whiner usualy do best.
#1 fol mana cost, you forget or simply ignore the fact that everyone will have the same ammount of mana. Ret will have a 100k+ mana pool like holy in mop.
#2 cant use TV without 3 holy power, you never did unless you were very bad. Good paladin used Inquisition with -3 holy power as a start up and its still possible.
#3 again hard casting exo is not a loss in a world where a 6 second cooldown 30 yard judgement gives you holy power and has its cooldown reduced by haste. Oh did i mention exorcism proc also give holy power.
#3 lost of an ok utility in holy wrath, but gained stuff like blinding light, snare, better laotl, more consistant damage.
#4 we actually gained better healing with the wog revert.
#5 less rng damage with most ability giving holy power.
In short, blizzard gave us everything we asked for but you guys wont be happy until they give us the freaking moon.
