zeidrich and Redcape over at elitistjerks have done new tests every time the ptr build has been updated. The current one is marked as retail, here's how ret works:
The Seal of Vengeance/Corruption dots, Blood Corruption and whatever the alliance dot is called are only applied from white melee hits, nothing else. Not crusader strike, or divine storm. This would be terrible for ret dps on its own, because any kind of target swapping (80% of bosses in ulduar) would destroy our dps what with a ~15 second ramp up time to get the full stack rolling.
However:
When it's stacked to 5, white hits, yellow hits, even judgements proc a kind of seperate SoV hit which is 33% (38 with seals of the pure) of weapon damage as holy, which crits double like a melee hit. This is additional, distinct damage to the dot and the attack that procced it. Furthermore, all attacks made while Blood Corruption is *partially stacked* will result in a partial seal proc. 6.66% weapon damage as additional holy at 1 stack, 13.5% at 2 stacks and so on. The judgement at 5 stacks is reported to be absolutely ungodly, almost like old-style judgement of blood.
This basically means that seal of vengeance is inferior than seal of righteousness (not command, more on that in a moment) before roughly 12 seconds and greater at all points after that, assuming a single target. Seal of vengeance as mentioned before will not proc from divine storm however, so where does that leave our AoE? Well, nerfed basically. Not hugely, because you may have noticed that consecration was the workhorse ability there anyway. Rets will however be forced to swap seals accordingly during and between fights.
Seal of righteousness vs command:
It's pretty simple. Command has been nerfed extremely heavily, the judgement is both much weaker and no longer crits stunned targets automatically. Unlike righteousness, the seal itself can crit and scales better with weapon damage and raid buffs however. Because
Seals of the Pure is an important dps talent now, Seal of Righteousness will outdo command on short duration trash, especially if you are expertise capped from gear and can take glyph of seal of righteousness over the 10 expertise vengeance glyph.
Edit: If you can think of a situation where you're dpsing 4 targets for a signifigant amount of time, the fact Command seals can crit will probably pull it ahead slightly. There are no fights like that though. On kologarn you'll still want seal of vengeance for the massive single target burst it can push out at 5 stacks.
We're pretty boned on emalon. Target switching every 30 seconds is fine, if you're applying corruption to each target. The supercharged add wont live long enough to stack it, but might live just long enough to let emalons dot fall off.
