If it's just this tiny increase to the base damage, will that affect its scaling with spellpower at all? Seems like just a very slim (~130 damage per star) across-the-board increase.

Current coefficients on LIVE are 5%+1.2%, not 21%+12%
[Megalon's] Starfall hits [Master's Training Dummy] for 1 Arcane.(458 Overkill) ( / 1.06 = 433.02 )
Min SF hit: 433
21% coeff?: 16*.21 = 3.2
Scaled hit: 436
With talents: 436*1.06 = 462
No clue how GC gets to 21% :C

Hopefully that Starfall Main-shot coefficient is missing something. Most current theorycraft was using about 46% for the main shot and 12% for the splash.

If the combined coefficient change is +17%, combined with the base numbers, 4k SP and 50% crit, 60s cooldown (glyphed) single-target DPS goes up by 60 over the course of a fight.

If anything, this might be enough to push IS out of our rotation entirely, swapping for the Starfall Glyph and going with Eclipse/MF rotations only. For me at least, WrathCalcs was already showing that to be the way to go, although I've been hesitant to make the change so far.

I can't say I'm not disappointed by this change. They seem hellbent on pushing through with the AoE mechanic of the ability when it's just really just not so useful in the long run.

Well, posted here:

In any case, this isn't going to change much meaningful for us. I was always recommending Glyph of Starfall, so that's not changing. The DPS loss it represents compared to Glyph of IS will be slightly smaller.

As I mentioned before, I noticed that my theoretical DPS with the Eclipse/MF/IS + IS Glyph was lower than my DPS with Eclipse/MF + Starfall glyph, although the difference is so minor that it is rather inconsequential. However, depending on just how much damage Starfall does, the Glyph of Starfall may outweigh the Glyph of Insect Swarm altogether, no matter the rotation. Although I highly doubt they'd increase the damage by such a degree, when you consider that we are already starting to see signs that an unglyphed IS is a DPS loss, this change may end up pushing IS out of our rotation.

I haven't been using IS in my stationary rotation since I got 4 t9, simply because it is a loss of DPS easily unglyphed.

That being said, another advantage is having it available for movement at(almost) all times without the need to clip it. This provides a great setup for fights that require a decent amount, which has a tendency to be all of the more difficult ones, simply because you aren't wasting as much of your stationary DPS time on spells that eventually get clipped.

The single target damage buff to starfall is nice, though...definitely gonna be good for pvp too.

New spreadsheets are up. First, current spreadsheet, with live Starfall coefficients made slightly more accurate to reflect the testing I did yesterday while I was looking into all this:

------

First of all, this is a significant DPS increase. Around 7% in my current gear (I'm not quite seeing the 800 Erdluf posted, more like 650). I wouldn't say it's overpowered; my impression is that it will lift Moonkin from the low end of hybrids to hopefully the middle of the pack. It's not entirely ideal that the buff comes in the form of Starfall, a spell that's awkward to use efficiently at some encounters, but I think we should be pretty happy. We were warned that it would be a PvP-oriented change, and we're all pleasantly surprised by the sheer magnitude of it anyway.

Next, this clearly puts Glyph of Starfall over Glyph of IS. I'll update the guide sometime soon. Use of Glyph of Starfall, but cast IS anyway (at a very small DPS loss) anytime the -hit debuff is meaningful. Overall, I'd make a habit of keeping IS on bosses.

Finally, this makes Glyph of Focus a contender. Not if you have 2T9--in that case you should still run Starfire/Moonfire, but once you move on to 4T10, those two become much weaker. Exact resolution of this question might have to wait until we further get into the issue that's been floating around about when it's worthwhile to refresh DoT's. Whether you drop Glyph of Moonfire or Starfire would depend on how often you actually make use of Glyph of Starfire. On paper though, the best Glyph combination in a Patchwerk situation will be Starfire/Focus/Starfall.

The buff to Starfall is really nice and needed. Let's hope it's not nerfed before going live because of pvp.

Glyph of Starfall is now better than Glyph of IS, but the Glyph of focus is a more complicated choice. It appears it's a contender if you consider the damage only, but it comes at a cost: an effective range of 18 yards. It has already been calculated that range increasing talents are a huge DPS boost. In a sense a "range decreasing Glyph" could be a DPS loss, and it's quite hard to model.

For example when using Glyph of focus, if at any time during a fight you have to move for more than 1 seconds to get closer to the boss to be able to use Starfall, it's a DPS loss.

Here is how I got this number: (napkin math)

Case 1: No glyph of focus:
One cast of starfall deals about 50k damage for 1 second GCD. After that you can continue to DPS normaly, let's say 10k DPS.

Case 2:With Glyph of focus, in a position where you are further than 18 yards:
n seconds of movement to get to 18 yards at low DPS (let's approximate that to 0 DPS since it doesn't change the result a lot). One cast of glyphed starfall deals 60k damage for 1 second GCD.

It's clear that Case 1 deals more damage as long as n > 1

From your post/spreadsheets it sounds like the question of whether or not Glyph of Focus is better than Glyph of Moonfire/Starfire is going to be determined by the individual fights in ICC, making it hard to determine mathematically. It seems to me though that the range penalty aspect of Glyph of Focus is going to make it significantly less effective than a spreadsheet would indicate (on most hard modes anyway), perhaps keeping it behind Glyph of Moonfire/Starfire.

I guess I don't know either. The latter way would be pretty weird though. Also, the max range is a "radius" due to the way the spell is implemented:
