No changes - I already use 4t9 and with the 2t8 nerf I see no reason to change. I did modify my gems slightly, going back to Potent over Reckless for good yellow sockets. I lost 120 crit rating when I picked up a second Reign of the Unliving, and with ICC as the primary focus I don't see a need to value haste over crit any longer.
After some deliberation I decided to go into Icecrown with my Anub spec.
This took some thought. I originally planned to go with something almost identical to the above, but without Typhoon and picking up the last point in Imp IS - that's a pretty optimized single-target build, but also with strong AOE. However, reading strategies it looks like a lot of guilds find unglyphed Typhoon to be useful on Saurfang - there are adds that can't be tanked and need to be CCed, and Typhoon is a good choice because of the knockback + daze.
You could also easily do a build with 3/3 Imp IS and 1/2 Gale Winds, but it appears that at least two of the first four fights will have a non-trivial AOE component (Gunship/Saurfang), so I opted to go 2/2 GW. One point in Imp IS is a relatively trivial single-target loss, while one point in Gale Winds is a very significant AOE loss.
So Starfall and Reign of the Unliving walk into a bar.
RotU: "I'm a trinket that procs from critical strikes, but only every two seconds.
Starfall: "What a coincidence - I can crit on a one-second period which exactly matches up with you. Maybe we can work something out?"
Silliness aside, the Starfall Glyph (30 second cooldown reduction, NOT the focus glyph) and the Insect Swarm Glyph have always been relatively close in value. My feeling is that with the neat little synergy between Reign and Starfall will make the glyph a bit more valuable, especially since I now use two of them.
If however you don't have Reign there are a few other reasons I changed to Starfall:
- Each one of the first four fights - and many of the later ones - have adds. Glyphing Starfall vs IS is a close call in a single-target situation, but as raids get complicated single-target situations tend to go away. Expect a ton of adds in ICC, which will increase the dps benefit of Starfall.
- Glyphed IS is important to keep up - you don't want 100% uptime but you should work it into practically every part of your rotation. Unglyphed IS is much less critical - you pretty much want it up during Solar Eclipse... and that's it. This frees up Insect Swarm as an, "oh, I have to move" spell - moving from fire? Hit IS. Icecrown will most likely have a lot of movement, so having IS available more often will help mitigate some of that otherwise lost dps time.
- 3% miss - I don't want to get into an avoidance vs EH argument, but suffice to say that 3% miss - while not being critical or even particularly important - is still, well, 3% flat avoidance. Your tanks can't depend on it but it might prevent a death.
Obviously any of the above might change in the future, but my goal is just to go into normal modes with something solid for all of the fights - for hard modes I anticipate optimizing on a per-fight basis, of course.
