Is anyone seeing Stay of Execution behaving weirdly with regards to haste?

It was my understanding that Stay of Execution is not effected by haste (via Dedralie over at Healiocentric). However, I toyed with it on my break and noticed that I was coming up short on ticks; I expected to see 10 ticks, but I was only getting 8. Granted, I only tested this a handful of times because my break is limited (I will doing some more extensive testing tonight), but I wanted to know if anyone else had encountered this behavior.

Nevermind; I was simply miscounting.

Edit: I need to proofread what I write more thoroughly. >.<

I was debating this, but I only just switched from lurker to poster here on EJ. I'm not sure I have enough clout to post a guide here, despite being a long time reader and player. :X

Never been a big poster on here but I was trying to figure out haste cap...I'm going spirit>haste>=mastery>crit and seems to hold up well in 25s. Keeping up with the OP Druids just fine. But everything shows mastery over haste but I feel in later raiding haste will still want to be priority. I almost always socket spirit gems now. Raid buffed I'm around 28.5%haste (4905 hate rating with most dungeon heroic and some raid epics) and about 25% mastery. Mana regen seems fine. With divine purpose procs its not a problem on mana if you get bad procs sometimes it sucks. LoD is awesome now. Im gonna keep with haste for a while maybe Try out mastery over haste. But my main purpose was finding haste cap. So then I can focus on mastery. Greatly appreciate it!!

Get enough haste until you feel comfortable.

As an example (and a more direct answer to your question), I'm aiming for at least 3506 haste rating, which is ~25% haste with raid buff. This puts all the main cast-time heals at just under 2 seconds (anything longer than this feels too slow to me), and happens to coincide with the 3rd tick of Eternal Flame. From there, I've been reforging to Mastery.

Edit: Fixed the haste rating; I was a few points off.

Hi,

How come haste is no longer the best stat before mastery?
Of course Mastery is great, "Illuminated healing" is always top 3 healing done, but i'm casting at 2.1sec while raid buffed.
Is that not too long? In term of HPS, how to determinate whether more Illuminated healing, or spellcast will be higher?

Mastery has one big advantage over haste in that it's very mana friendly; you are getting additional "healing" (absorption shield) at no mana cost (where as with haste, more casts = more mana). And absorption/damage prevention has the benefit that it can't "overheal" in the traditional sense; as long as the target is still being dealt damage, the shield will prevent additional damage, meaning less healing is necessary on the target (which means you can follow up with a cheaper heal). This is important since, for the moment, "mana matters."

Cast time is also important however (if you can't get the heal in before your tank dies, the shield is meaningless) so as I said before, get enough haste until you are comfortable. Note that "comfortable" means you are getting the necessary healing to the right targets in a timely manner while not running out of mana. For me, that's at least 25% haste raid buffed, but it might be different for you, so experiment a bit.

As far as a throughput breakpoint for haste vs. mastery, that is entirely situational and hard to quantify from my understanding, and I haven't spent enough time yet in raids to even guess at this.

Healing stats are such that your playstyle will tend to make the most difference in how you value stats, and as such you shouldn't look at which might be arbitrarily better but instead look at what benefits your playstyle the most then go for it.

Trying to get empirical stat values for holy (and most other healers I'm guessing) is simply mental masturbation. Yes, this is a theorycraft site, but the fact is there are different ways to heal effectively and enough different encounters that one single way won't work for all of them. Because of that fact there will not be a clear winner or even priority that we can use in enough situations to reliably say "gear this way and you will win."

Got the maths in a viewable spreadsheet? I have 1646 haste at the moment unbuffed and I'm getting the Sacred Shield (apsorb part) 6 times, the 6th is coming literally as SS itself falls off.

Note: Light's Hammer and Execution Sentence don't actually scale with haste, so ignore those on the table. Light's Hammer should always be 16 ticks, and Execution Sentence should always be 10 ticks.

Edit: I left a note for Binkenstein (author of the tables linked above and an overall brilliant theorycrafter) to update the holy paladin one specifically for the level 90 talents, so you should see those removed from the table at some point in the future.

Why would you use HA though?
