3 different holy specsFollow

The thing that instantly strikes me is that the sub-ret spec is more for having fun in heroics with lots of crits and none of the prot tools. The 20 points in prot spec would be much better for main tank healing in a raid since you have a much more powerful sacred shield, more personal healing and divine sacrifice to combo with bubble/D. protection for huge boss aoe attacks. So it really depends what you actually find yourself doing more, heroics or raiding.

If you go with the sup-prot spec, i would probably change the third spec slightly to this:

No improved conc. aura, but improved blessing of wisdom and lay on hands (our holy pally said it was a very nice cooldown to use when we were doing things like festergut and blood princes). You don't really need improved devotion aura considering how common prot paladins are, and if there isn't one in the raid there will likely be a resto druid anyway for the healing buff.

Thanks! I'll stick to ret then =)

Well this is an alt and I'll be used to playing a character with no movement increase (my death knight) so any issues with learning how to move in and out of mechanics on my paladin won't be an issue, since I know the fight already. This is just my alt.
