I think that the idea is that a paladin should have a choice to spec in different trees and still be considered viable in end game. Solo play as a ret spec is not a problem now, and they have made many improvements, but unless geared very very well, Ret paladins are not often taken seriously as a DPS addition to many groups. Its not that we want it all at once, just the ability to choose. Otherwise, what is the point of Ret spec at all?? Redundancy? Like say, a plate back option in the AH?

When your damage potential is balanced against your ability to heal lacking the means to do so is a problem.

Why? Because you gear yourself up as a DPS Warrior, Blizzard's own declared purpose by the way, and until recently support for that kind of itemization was poor. Consider that it takes 840 mana for a 2.5k heal for a Ret Paladin who has 6-7K mana.

That's the baseline current max rank of Holy Light. Without Spell Damage of course as Retribution is moving away from that, and we're not being left with any options to boost healing potential.

Well, at least your name is apt.

I found it humorous how you think Ret Pallys can actually heal properly. Honestly we go oom after a couple of shitty "big" heals. And btw plate only help against rogues and cat druids for the most.
