On Anub topic : We have 2 unholy DKs, 3 FFB mages and usually 2 (or more) rogues. That helps shortening the AoE phase obviously. I don't think it is possible to get Anub to 30% with only one burrow phase in 25HM (never saw a video of it) so we get him to 75% first burrow, 50% 2nd burrow, and that way we don't have to wait to AoE the 2nd wave (less time with the adds alive = less troubles with the Shadowstep interrupts).
If you are able to channel three 5-targets Hurricane, you really should spend a point in Typhoon (Typhoon + NG'd Hurricane > non-NG'd Hurricane).


On RotU topic : the queueing system works wonders on SF (since you can't usually bring it close enough to 1sec cast even under Heroism+Speed potion) which means that if you chain SFs the right way (spamming the key like your life depends on it as soon as you get past gcd - or even before if you are a bit hyperactif like me) you have virtually no loss from latency (as long as you don't have more than 1sec of latency obviously).
So yeah you can trust the cast time you get theorically to be right. Which means that if your get over 400~ haste + talents and full raid buffs and you perfectly chain SF and get a crit every time, only half of the cast will proc a mote. Trying to hold back for 0.1sec manually seems quite tricky to me (as well as unnatural) and I don't see how it could be a dps gain since it could very well push a SF out of the "Lunar eclipse window" thus nullifying most - if not all - of the gain. However, applying DoTs during Lunar should be a good idea, even if you have to let them fall off a few second. The best way to apply them would be one at a time, queued after a SF.

I'm looking forward to the NG change that was hinted recently (in a blue about the poor scaling with haste the Resto Druids experiment), it might also solve alot of our limitations with haste scaling..

But you're throwing all the mobs out of the ice patch, don't you? I don't understand how this should be useful.

I would still keep 2pct8 for the times where single target is important. For instance after the first set dies, ranged stay on Anub until he burrows, between add killing in p3 you single target Anub, after the last set of adds is ignored and scarabs in p2. There's enough single target dps on the fight to not discard your biggest single target boost for ~85 sp and 60 spirit.

Also in reguards to mana regen on Anub, I basically just use my own innervates, and since healing is so light until p3, mana regen isn't really a huge deal and I can generally steal our feral's innervates.

To expand on what was said here. If you were to get the Abyssal Rune, both of your trinkets would then have the ability to proc at the same time, which is huge. This not only allows you to have +1180 SP but also allows them to proc more often.

I would also recommend opening with IS/MF and keep them up as much as possible, in the rotation you listed above you don't apply IS/MF until after eclipse procs, thus you are losing DPS while the DOTs aren't up.
