hey guys been looking all over the place for new 3.2 builds for leveling. Used to use Jame's guides but now i cant find anything that works well. i want to be able to level as fast as posible and i am using blood right now but find its not great for aoe. any spec suggestions and rotaions?
In general, my advice on dk leveling/specing is don't worry too much. Each spec easily has enough dps/survivability to make life pretty easy. If you grab any of the major dps specs one of the trees and go down it as far as possible for your level in the primary tree you're pretty much good to go.
Some possible specs to shoot for (this comes with the HUUUGE caveat that these are not the only viable specs, there are several variations to these to understand the pros and cons is a non-trivial endeavor that requires either heavy forum reading (the ubiquitous EJ threads are good for this) or leveling yourself a 80 dk and getting a hang for the abilities, preferably both):
DW Frost 0/53/18
2h Blood 51/0/20
2h Unholy 16/0/55
One thing I do want to point out, since these are raiding builds they don't include two of the talents which do actually have a non-trivial effect on leveling. For the purposes of killing/surviving/soloing/downtime, none of the three trees has massive advantages or disadvantages. Unholy however includes On a Pale Horse and Improved Unholy Aura, which give the advantage of moving you to and from quests and questgivers faster. If I had to say which is the fastest leveling spec, Unholy probably wins out simply because it has less travel time than the others.
As for rotations, pretty much every dk rotation works roughly the same way. 1. Put up/refresh diseases (IT, PS, Pest) > 2. use whatever runes are left on abilities buffed by diseases (BS, HS, HB, Ob, DS, SS) > 3. Spam RP based abilities (FS, DC) until your runes are back off CD > Repeat 2/3 until your diseases need refreshing then go back to 1.
If you ever need to solo elites or other not-generally soloable mobs, hit Frost Presence and run your normal rotation except use DS in 2 whenever possible over the other options.
I leveled ridiculously easily as a full blood spec DK. The self healing is really a bit outrageous. I rarely found myself below 95% life after killing any reasonable number of equal levels mobs. Partnered with glyph of death grip (resets the CD on death grip after HK or exp kill) I was pretty much non-stop pulling/killing/questing.
I'm sure other methods work well, just sharing my experiences.
