From the latest patch notes:
Spiritual Attunement: Removed from trainers. It is now available deep in the Protection tree for 2 ranks at 5/10%.
I don't speak for all paladins. In fact, at this point in the game I probably speak for very few of them. I belong to the Hybrid faction of paladins. It's probably because I created my paladin so many years ago, when the class was very different.
The Hybrid faction holds that the paladin should not overspecialize, that the baseline 0/0/0 paladin should be minimally compentent at healing, DPS, or tanking. Not raid-viable, but minimally competent. A Ret paladin should be able to heal a little bit, to tank at least the normal instances and group quests in the proper gear. In a pinch, maybe even play a small part in a raid. A levelling paladin should be able to handle all of these roles, regardless of spec.
I've tanked Tidewalker murlocs as Holy. I've healed as Protection. I've tanked all the normal Wrath instances as Retribution. To me, being able to do all this is an essential part of the paladin identity. I understand the need for specialization in the current game, but being a hybrid--being able to contribute to a role that we are not specced for--is still important to some of us. It's why we chose this class over all the others.
But for this to work, the baseline paladin must have access to all the necessary tools. For healing, we need Flash of Light and Holy Light. For damage we need Judgement and a damage Seal. For tanking we need Righteous Fury and Spiritual Attunement. By themselves, these tools alone will never make us raid-viable or preferred. But they allow us to try.
In the past, Blizzard has understood the Hybrid perspective. They gave us talents like Sheath of Light and Touched by the Light that allow the non-healer specs to heal more effectively. They reworked Fanaticism when the threat reduction was introduced, so that Retribution would still be able to tank.
Holy needs Spiritual Attunement to tank, to fulfill the hybrid nature of the paladin. Retribution at least has a replacement with Judgements of the Wise.
Maybe this doesn't matter in a world of specialists. Maybe dual-specs puts the final nail into the paladin-as-hybrid coffin. But I hope Blizzard reconsiders removing Spiritual Attunement from Holy's reach. I know that Spiritual Attunement is broken for a healing paladin and raid damage. But I think that there are other, better solutions.
My suggestion is to fold Spiritual Attunement into Righteous Fury and add a penalty to keep Holy from using it. Turn it into more of a true tanking stance.
24% of base mana
Increases the threat generated by your Holy spells by 90%, but the amount healed by your spells is reduced by 50%. When healed by other friendly targets' spells, the paladin gains an amount of mana equal to 8% of the amount healed. Lasts 30 min.
Alternatively, rather than a 50% reduction in healing power, maybe you could condition Illumination to only work when Righteous Fury is not active, just like Fanaticism. The baseline paladin could still tank if necessary, but the extra threat makes RF unattractive to a dpsing paladin, while the healing penalty makes RF unattractive to the healing paladin.
Even if you don't like my suggestion, I hope that you understand my perspective on the paladin class. It may not be a common perspective anymore, but I think it is still of value.
