I've played both Holy and Disc spec for years but over the past 6 months or so I've really come to enjoy Smite healing when running 5 mans and when appropriate in other scenarios. 

So last night I was playing around the new MoP Talent Calculators on WoW's site and could not find Attonement (talent used for Smite healing) or any other talents / abilities that grant similar healing effects to Smite.

Smite healing really made healing fun for me again and I would really hate to see a cool mechanic like that tossed away.

I'm really hoping that I missed something.

Those calculators are far from finished, theres huge amount of things missing at the moment.

For the most part however they seem to plan to keep most specs as they are now intact.
