I take 'viable' to mean 'most time efficient method of levelling to 80'.
I am currently leveling my second priest as disc. There are no changes to talents or glyphs that make this a time efficient practice, IF you intend to quest or dps down mobs in the usual manner.
The 3.3 changes to the dungeon queuing system have transformed leveling speed for a healing-spec priest, however. I use the new random dungeon tool which in my battlegroup has seen an average 30 second wait for a healer wanting to run a WotLK normal dungeon, or last week, an average 5 minute wait for a BC normal dungeon. Anecdotally, the wait times for DPS classes are much longer. Instant teleport to the dungeon, and steady grinding of high xp trash mean that using this new feature may well be the most time efficient leveling method for a priest of any spec. Either healing spec would come out ahead of shadow for time efficiency if the queue times across all battlegroups are significantly shorter for healers.
the question of lvling disc is an interesting one to me....I lvled holy (which was a no-no, get over it...lol) and I healed instances constantly....I noticed that I could actually put out decent dmg this way, but my mana pool slowed me down when doing dps, but at the same time, healing groups was easy...so momo's note on how fast you'll get groups as a healer is a really important one...
that being said....now that I'm disc, even though shadow is my off-spec, I don't even bother changing it when I solo....my survivability is awesome in disc, and my dmg is nutty good (not as good as holy or shadow, tho), and my mana is much better than it was in holy or shadow, so part of me wonders how much faster I might have lvled if I was disc....the cautionary note for me is that until hitting penance and a couple key things in the disc tree, I'm not sure it would have been faster, or anywhere near as easy to heal groups from disc....disc doesn't really shine until you spec through the tree....but it was around lvl 60 that lvling as holy got really hard, so I lvled 60-80 almost entirely in instances....that is also the time when disc can pick up some of its fun stuff, so maybe questing between instances would have gone faster....
as most people end up saying, do what you like....if its fun, it'll go faster....the only mechanics to be aware of are the basic differences....until high up in the tree, disc doesn't have the fun toys we all attribute to disc, and holy gets boosts to spellpower and group heals pretty early on in the tree....unlimited shields early on for disc, bigger dmg from holy fire, smite for holy spec.....
having recently lvled my DK as a tank, it was interesting to be healed by different healers while lvling, and I must say that while a few disc priests at lvl 70 or so did really well, most of them just failed....but that may have been because folks doing disc pvp spec run differently, who knows....again, its more about the player than the spec
and I must say that at major changes in the tree (getting coh or penance or shields, etc) some respec'ing can shift things....I end up respec'ing at least once every 10 lvls....sometimes to try new things, sometimes to take advantage of something that just became available...so those are major nuances that benefit each tree...the variety within each tree is really big...
if you lvl disc, post ur experience cuz i'd love to hear what it was like, what you used and what was fun!
Hopefully that should answer most of your questions in regards to holding aggro. Personally when I pull, I'll AS three, the ShotR the one that didn't get hit by AS, follow that up with a HotR, then just continually keep tab targeting so:
1. You can keep track of which one the DPS are killing so you can focus on that particular mob
2. You refresh SoV/SoC stacks on every mob. 5 stacks on each mob is very powerful for aggro generation.
One day this Thread magically disappeared. It has been a couple months and I haven't seen any sign of it reappearing. It would be really nice to have an Elemental Shaman Theorycrafting Think Tank again.
What is a good threshold to start following the ArP hardcap? Actually I am at 913 ArP (and I could reach 993 replacing a few Agi/Crit orange gems) but I'm not totally sure if it would be better to just replace some ArP gems with Agility gems while sitting at the ArP softcap with the Needle-Encrusted Scorpion (722 ArP + NES).
So, at which ArP value it is a good idea to start trying for the hardcap?
I've been hearing that the NES uptimes are poor compared to GT or MR. In particular, it has the same cooldown / duration, but the proc is 10% chance on crit. Some very rough math on my part (assuming 2 attacks a second and a 50% crit rate, 45 sec ICD) imply slightly less than 20% uptime--but I've seen logs from slow-weaponed warriors with 5-6% uptime.
Has anyone taken a WoL with it on in a raid setting? Can it proc from bleeds? Will this dsync enough to make using 2 ArP trinkets worthwhile?
I've been trying a few simulations with SimulationCraft:
1) my current gear/gems + DMC:G + NES = 7767dps
2) my current gear, 5 10agi/10crit gems replaced with 5 20arp gems + DMC:G + NES = 7758dps
3) my current gear/gems + DMC:G + BoV = 7878dps
4) my current gear, 5 10agi/10crit gems replaced with 5 20arp gems + DMC:G + BoV = 7859dps
So arp softcap + NES seems to be weaker than 913 fixed arp and this is weaker than 993 fixed arp if you drop some socket bonuses filling yellow socket with red gems.
hi i got a few enhancement questins
i swithed to enhancement 2 weeks ago (cause elemntal dps sucks)
