01/07/2013 09:28 PMNo, it really is not balanced. You're either really just not getting it, or you're blatantly ignoring the fact that we have many times said that operating at 75% (in fact, you're operating at a lower percentage because the 25% doesn't take the utility given by each into account) is not okay. No other healer has to choose between tank healing at 100% or raid healing at 100%. They can do both at 100%. Holy Priests cannot.

The '75%' is being thrown around a lot. So let's check it. We'll use 24k spellpower, 16.66% haste, 20% critical, 15 points of mastery.
A Discipline Priest performs their single target healing with PW:S (88,457), Penance (102,236 + 11,715) and Greater Heal (125,059 + 19,378) in conjunction. If we PW:S, Penance, Greater Heal 4 times we'll consume 1.07 sec + 1.43 sec + 1.79 sec + 2.14 * 3 = 10.72 sec and be ready to cycle the whole thing all over again. That's 780,156 healing/shielding in 10.72 sec, or 72,776 hps.
Note: I modeled Inner Focus as adding +8.9% (1/9th of the remaining 80%) critical to Greater Heal for simplicity. Grace was included on all heals.
A Holy Priest uses Flash Heal (80,447), Greater Heal (107,263) and Renew (74,139). Rolling in a 2:1 FH:GH ratio and tossing Renew when it expires, that yields 14 Flash Heal, 7 Greater Heal, 3 Renew = 2,099,516 healing in 30.0 sec. Which is 69,984 hps. If you include the Lightwell Renews available, you can add another 15206 hps. We'll ignore those.
Now let's drop that Holy Priest into Serenity Chakra. The casting time (and upfront hit) for Renew will disappear, so we'll just get a flat +8173 hps from Renew. We'll use HW:S (63,615) on cool down and otherwise rotate FH/GH. Our effective critical rate for non-HW:S rises to 35% (60% uptime on +25%; it's a bit fuzzy), so our total healing rises to 2302581 healing in 30.0 sec for 76753 hps. Since all of our healing is affected by the Chakra, that becomes 95,941 hps. And, of course, those Lightwell Renews are still sitting out there as a possibility (they are unaffected by Chakra).
So apparently single target healing Holy vs. Disc goes from 96% to 132% (in that rough vicinity at least).
