There are 2 things making me consider a full haste build, for 10m. As spamming HR in 10m is less of a thing than 25.
1: EF HoT no longer giving mastery.
2: SH giving judgement HoPo.
So a full haste build, combined with Selfless Healer, will reduce the cd on both Judgment and Holy Shock, both giving HoPo. Especially since the last data mining shows that the Selfless Healer buff also working on Holy Radiance.
I fully intend to mess around with haste builds on the ptr if it looks like it will be more effective. I'm not that much of a Luddite.
