08/01/2012 04:32 PMI personally think of Unholy blight useless out of pvp. As blood boil will refresh the duration on your diseases, so I rather refresh + spread + deal damage, although on heavy aoe fight, plague leech seems very appealing as you'll be able to use your diseases and gain a crazy amount of runes.

There is a 25sec cd on Plague Leech, so you can't just get crunk on death runes in an aoe fight. Unholy blight isn't very attractive, so your not missing its usefulness, but i think you are over valuing its competition.
Rolling Blood (Hefizar pay attention, as this is also an answer to you)
This looks attractive for 5m content at first glance, but look at what you actually gain and it starts to fall apart. You pull adds, you use outbreak>blood boil to spread diseases. You now have all targets infected with the tank debuff and you only used 1 blood rune. From here on out the benefit of Rolling Blood is 0, since as long as you use BB to refresh the diseases on all targets you wouldn't have needed to pest after the initial one anyway. Total benefit from that talent = 1 blood rune over the whole fight.
Compare this to Unholy Blight, which affects all adds with the debuff free, so you didn't have to pestilence or blood boil to spread diseases. The scenario with Rolling Blood also got in dmg from a BB, but with unholy blight you can use a heart strike with that B rune instead, which will give you more aoe threat/dmg if there are not too many adds. If there are a lot of adds then you would BB anyway making them equal. This puts UB > RB (but not by much. A lot of these talents just happen to be the lesser of 3 evils)
The other option is Plague Leech, which is the talent i have as optimal in the default single target raid spec. The reason it is not optimal here, is that in order to gain a D rune for free, you need to be able to re apply those diseases with Outbreak. If you have to use a pestilence then you only trade a D rune for a B rune every 25 seconds, and if you have to re apply with icy touch and plague strike you are getting 1 death rune for a frost and unholy runes. That's just bad.
Since outbreak is on a 1 minute cd, you will only benefit from this talent, even in an aoe scenario, once every minute. 1 D rune per minute is not exactly fantastic, and the only reason it's optimal in the non-aoe spec is because both the other talents are aoe only.
This puts Unholy Blight above Rolling Blood and Plague Leech for aoe situations, which is why I have it as the default talent for 5 mans.
08/01/2012 04:32 PMI'm still very skeptical when it comes to Purgatory, mainly due to the fact that I've yet to actually see this talent in action. If its a high number, I imagine this will be useless outside of 25m raids. Since stuff hits harder (so there's a higher chance of this being used), not to mention you'll have more healers so they can probably burn out the absorption shield and heal you up to a nice amount before the next melee ability.

It all depends on how they tune stuff in relation to how they tune DK tanks. I'm going to assume 10H will hit hard enough to make spike damage a threat, at least early on, so I decided against making a 25m spec and a 10m spec and having purg on both. Though you are right, purgatory does favor 25m. We will just have to wait and see how things are tuned for release. because right now they are all over the place which makes it hard to assess the spike dmg threat on tanks for 10 and 25.
08/01/2012 04:32 PMAlthought I thought for Conversion it only used up the Runic Power when you originally cast the skill. Meaning, lets say you used it at 40rp, so you get 4 ticks out of it, but you can still gain rp, lets say you got 30rp during that Conversion phase, you still only get 4 ticks. Correct me if I'm wrong. I haven't tested all talents in the beta yet.

You're wrong :)
I tested this one a lot and actually really like it. It's still not valuable enough to justify using it over Death Pact in most scenarios, but I really do like the combo of VB and conversion. Heres how it works:
Provided you have enough RP for at least 1 tick, you push conversion and you start sucking RP. You continue to convert RP into health until you either toggle it off (which is off GCD btw) or run out of RP. There is no CD for this, so you are only limited by your RP. You wouldn't want to have this on a lot, as you are taking RP away from Rune Strike and thus RE procs, but as a cooldown it may still be valuable in some fights.
