Why not? Innervate and Mana Tide as mentioned in the article are better mana return (I'm trusting the writer here, not sure on the numbers) than Divine Plea. As also mentioned Innervate can be used on anyone in raid, and mana tide affects 5 people. Neither of these have an adverse effect, why should Divine Plea?

mor8idhomogenosuicide, Innervate can be used on others so it's not wise to use it yourself on CD. There's no sense in having such a spell being used on CD because it doesn't requires skill and it's not fun. If paladins need more mana, Blizz can just make paladins' spells cost less and remove Divine Plea at all.

Divine Plea is useful only when you need to find appropriate time during the fight to use it. And it actually fills the break when you aren't casting healing spells with something meaningful.

Mana Spring Totem on the other hand is just a buff. And retribution paladins have a talent for it too.

@Orlan

Mana Tide and Mana Spring Totem are two completely different things. Check them out on wowhead.com.

Orlan - I appreciate your comments, and I can definitely see where you're coming from with your point. BUT - and as always this is personal opinion - the whole 25% of your Mana was about right for us! We got the odd few fights where we needed to use DP - be it due to bad healing (which we're all guilty of on occasion) or simply the God of RNG not being in a good mood.
We could cover that 50% output drop with Angel Wings (or I did at least) and at the time I used to proc and drop my Darkmoon Card for another 2000.
10% to be honest is not going to cut it - especially with the death of Illumination!

and @Fairlane below - I think we all did that at some point mate!

Stop downrating this guy just because you want your Divine Plea back! He is 100% RIGHT. If there is no penalty to using it and it can't be used for someone else's benefit, a la Mana Tide or Innervate, there is NO REASON NOT TO USE IT ON CD. None of you who are downrating him could FIND a reason not to use it on CD if the debuff was gone. The only possible reason not to use it would be "My mana is full" in which case, why do you even care about this ability anyway?

When there is NO functional difference between hitting an ability on CD and adjusting regen numbers to recreate the effect, then that ability is boring and superfluous. Bliazzard WILL NOT and SHOULD NOT remove the healing debuff. If they are going to do that, they will just kill the ability and ramp up our regen, which is where it should go anyway if they're going to keep it in its nerfed state.

Oh, and Chase? 20% of 25% is 5%, not 10%. Divine Plea has been nerfed to 40% of Live, not 20%.
