Healer, 2P -- After using Power Infusion or Lightwell, the mana cost of your healing spells is reduced by 25% for [10|15] sec. (10 sec for Discipline, 15 for non-Discipline.)Healer, 4P -- Your Power Word: Shield has a 10% chance to absorb 100% additional damage, and the cooldown of your Holy Word abilities is reduced by 20%.
The holy set bonus' do not look very appealing at all, but since I do not play holy really I on't comment further.
As for the Disc bonus. The 2pc seems viable. Especially on healing intensive progression fights where disc will use PI as a self buff for efficiency and throughput.
The 4pc is rather terrible though. Majority of players hate the t10-t11(after shield buff) style of stacking mastery and spirit and spamming shields all day then bringing 2 resto shams and 3 shadow priests and 2 holy priests just to feed the disc HOH/Tides all fight long. Plus it's just boring to play. PLUS you guys DONT like it. You try to take it away with dramatic increases to the spell cost, but we do it anyway until you cut the duration in half and to a greater degree when stat scaling in new tiers combines with a few different approaches to some of the encounter mechanics leaving Shield spam finally behind other methods of healing so the min/maxers give up on it. (Thank goodness it was boring doing that for 18+ months.)
And this brings us to now. Disc healing feels good. I use all of my spells on a regular basis. I cast everything in my arsenal and it's really fun. This 4pc would promote frivolous shield spamming by those not intelligent enough to realize wearing 4pc would likely be a throughput loss unless you compensated by making the stats on all healing priest tier perfectly itemized.
Let me just post my idea for the disc 4pc before I drone on and on for ever. Your power word shield absorbs 100% increased damage. 10 second Cooldown.
Bam Fantastic non RNG, NON Spammable throughput upgrade for disc. Maybe make it 11 seconds CD even .
Thats win right the you have to be able to top T12 4pc which was/is AMAZING. Please consider my idea. if it's too powerful you can always reduce the % increase.
Thanks. Love disc. Please dont ever ruin it!
