Regarding WoG, you said it is intended to be situational among other things. If so, do the developers still think the almost non-existant state of Ret combat healing is currently acceptable?
Yes. Many of the problems we've had with Ret are of the "one man army" category, where a paladin can do a lot of damage, then go defensive and heal themselves up. We love the kit of the paladin who can heal as well as do damage, but it needs to be tightly controlled. Word of Glory gives us that control. We have the room to make the spell really powerful because we know its on a tight cooldown and you sacrifice dps to use it. We can't do that today with say Flash of Light, because once you can cast one strong FoL, you can cast a bunch of them until you go OOM (at which point you Judge or Divine Plea, and you're going again). Similarly, we can make Selfless Healer nearly overpowered because you can't use it on yourself and because even with it you're not going to out compete a Holy paladin in healing. If you can occasionally contribute to group healing in tight spots, then that's great. That's some utility you can provide. (Note: Don't oversell this as "I'll get brought to raids because of my healing.")
Less grating, but probably more important, Divine Purpose's rng on Holy Power generation could seriously mess with sustaining a rotation. A protracted dry spell will leave you out of usable spells for significant periods. I'm sure this will all balance out over the course of a standing fight but it will still be annoying and inconvenient.
That's the wrong view to take though. The equivalent would be "I'm balanced around getting a crit every swing, so when that doesn't happen, RNG screws me." You get a Templar's Verdict every 3 Crusader Strikes. Sometimes you get lucky and need fewer. You of course need to pay attention for when that happens and be able to react to it and alter your immediate plans. That right there is the element we think is most missing from today's Ret paladin.
I don't have anything really useful to add, but I'm glad that someone at Blizzard understands that the word "judgment" is spelled incorrectly in-game.
I've been tempted to change it soooo many times. :)
The amount it heals is most definitely balanced around how good it will be for Holy.
Those numbers don't have to be the same though. The new talent tree design affords us a lot more flexibility in that regard. Part of the reason Word of Glory is so useful to Holy is because it costs no mana. Ret doesn't really care about mana, because it comes and goes easily, but a Ret generally won't be able to sit there and queue up several Holy Lights in a row. They will be able to sometimes use a Word of Glory though.
