From the Dev Q&A
Question:
"Is Word of Glory still going to be on a 20s CD for protection paladins? With the new active mitigation paradigm, it would seem "paladin-ish" to heal myself every time I can (or to choose a heal OR a holy shield)."

Answer:
"Word of Glory does not need a cooldown in 5.0. Prot can choose whether to use it for healing, Holy Shield for absorption, or Shield of the Righteous for block."

So there we have it, What we have all be waiting to hear. No more constant CTC and a flexible choice. Looks like in 5.0 we will be juggling mitigation/dps . I guess by doing all out for as much mitigation as possible and having low DPS wont matter as the threat change means aggro wont be an issue.

Don't forget that Hunter pets (specifically cats) also buff STR/AGI with a 100 yd range.

Are there any opinions on the weapon that drops off Madness of Deathwing?

Since PTR refuses to run without crashing if I enable any addons, I figured I'd ask here.
Has anyone been able to test the 2pc and whether Glyph of Judgement is as good as it seems on paper there?
With no logging addon, I'm basically stuck with a gut feeling and some quickly flashing number which make it hard to work out in a realistic raid setting.

Considering we currently use 1 or 2 threat glyphs, and since our threat generation has been increased, I can't see why we'd run with SoR or HotR/CS glyphs when we can glyph for another increase in survival.

Could u please give me an advice about new T13 tanking trinkets? Need to choose 2. I bet all the tanks would choose Indomitable Pride - Items - Sigrie? but what about the second? There is implemented very good trinket for all other tanking classes Soulshifter Vortex - Items - Sigrie, but prot paladins should be already block capped or nearly. So what should we choose? Get a trinket from old content, or use an awful trinket for dodge Resolve of Undying - Items - Sigrie, or change our gearing model to make the proc useful?

What will u choose?

Look up Theckd's work on maintankadin. He has more numbers than you can process in one setting regarding pretty much every permutation of rotation. These threads summarize the optimal rotation but if you want to know approximately how much dps you lose/gain with a combination of Inq he has tables upon tables of sim results.

Why is Resolve of Undying awful? It doesn't have an active use, I'll give you that, but 990 static dodge is just incredible from a trinket alone. I haven't been on the PTR yet but if the current trend continues, in which stam trinkets are pretty worthless for paladins (and one of them even procs mastery), it's best combined with the 1650 VP trinket.

The real bursts in damage intake are usually caused by boss hits coinciding (in most cases) with elemental damage, in which case avoidance is useless, I agree stamina will always be valuable for that alone. Firelands was pretty elemental damage heavy compared to earlier instances this expansion, so I'm guessing it boils down to how melee and elemental damage ratio's will turn out to be in Dragon Soul.

That being said, it doesn't hurt to try pick up an extra trinket for swapping around depending on the bossfight. Also, I think the stamina trinkets seem pretty weak. The mastery proc of Vortex as said by gnumme is useless for any FL geared paladin, and I'm not really sold on the 54% last attack damage shield from Indomitable Pride. As you said those attacks that bring you to 50% will often be a succession of multiple hits, if a 20k hit brings you below 50% you'll get a 10k shield, 10k dmg absorbed per minute. If that would have been a generously large Ragnaros 100k hit, that would make a 54k shield. That starts looking like something but it's not reliable enough to really make or break that much. Personally, I'd much prefer an avoidance clicky, but I may be nitpicking.

The first trinket slot might as well be reserved for Mirror. We may use the VP trinket (reforged to dodge or parry) for fights without a use for Mirror's clicky, but you probably want to build your progression gear around having Mirror. The heroic trinket from Deathwing isn't really worth considering, because it won't be progression gear, so you're really talking about 880 dodge rating (unreforgeable dodge rating), which is probably not going to be a good swap.

The second trinket is either stamina or DPS, depending on the needs of the encounter. We don't need another mastery trinket, and can't use it. Indomitable Pride is clearly the better of the two high ilvl stamina trinkets, so the only question remaining is whether the unreliably sized shield plus 125 stamina is worth more than the controllable heal from Scales of Life. The answer is: It depends on how effectively you use the heal from Scales of Life.

Good one I'm still using it alot and 400 resistance for 10 sec on a 1 min CD is a major advantage in FL for alot of fights not sure why I didn't bring it up
I'm not sure how other paladins are doing it, I just bound Scales to WoG. Coming from a DK I tend to react pretty quickly to sub-35% drops and just push WoG, wether Scales is up or not. On the other hand, not having motivated raiders and forfeiting on Raggy hc, I haven't used it once since and just stuck to my mastery reforged to avoidance trinkets as I feel for current content 200k+ raidbuffed is more than plenty.

DPS reports for DKs are reflecting a 15% proc rate. I haven't seen any logs which reflect how it interacts with prot abilities yet, however any melee ability that hits appears to proc it for DKs.

World of Logs - Real Time Raid Analysis

For us I guess that would be ~20 CS, ~22-24 melee, and possibly 7-8 Shields per minute in any given stand still fight (Ultraxion), or roughly 7.5 ppm (or for true ppm [60 / 2.6] * 0.15 = 3.46 ppm on melee - unbuffed, no talents, etc.). Figure 210,000 health * 1.5% = 3,150 damage * 2 * 1.06 = 6,678 healing. Or roughly 400 dps and 835 hps. Rough napkin math, obviously, and I'm not 100% positive it works with SotR, but it's probably safe to assume it would.
