So..
As we all know, Paladins have the passive ability(Spiritual Attunement) to receive mana from heals, useful for tanking...
Retribution Paladins have Sanctity Aura which increases both his DPS and increases the Tankadin's threat..
Holy Paladins... well..... it could just be me, but i often find myself struggling to heal Tankadins, maybe they require a higher level of gear compared to Warriors or Druids in Heroics?
So, my point, to improve overall synergy between all 3 Paladin specs, i'd like to see the passive ability(Spiritual Attunement) that allows us to recover mana be modified to receive more heals from a Paladin class, i.e., 5-10%
Thus making Healadins more effecient healers for MT Tankadins, and could provide the Tankadin with even more mana which helps it tank for abit longer.. seems win-win to me.
I believe that would greatly improve the synergy of the 3 specs, though 10% maybe consider "OP"(when have paladins ever been considered OP, though?)
Ofcourse, with the Impending removal of Sanctity Aura in WOTLK, that renders half of my idea useless.. bloody updates >_<
P.S., modify Avenging Wrath to be a group/raid wise ability to buff all Paladins without effecting their personal cooldowns, allowing us to make up for the loss of Sanctity Aura(yes, i know that it's been intergrated into all spells anyway, but i like buffs!)
