I'm not in beta, so my sources are second or third hand.
Dreamstate disappeared from the Wowhead baked-in list.
Wowhead shows a baked-in Moonfury with 25% Nature and Arcane spell damage. I'd assume that includes Spellstorm damage, but since we can't get Starsurge without Moonfury, you could code it either way.
I'd argue that Innervate should be counted as MP5, and not as more starting mana.
Base thorns damage (Basic calcs page) is way up (8x or more? Need to find it.) but scaling is below 1%.
Eclipse impacts all Arcane and Nature damage, so a rotation that has 100% IS uptime, and 25% Solar uptime should probably see its IS damage increased by 1+25%*EclipseMastery.
Note: I'm not sure if DoTs gain the Eclipse bonus when cast, or when they tick. I've heard reports both ways, and have not seen raw test numbers.
I think there are potentially four interesting major Eclipse strategies in a generic fight:
1) Rapidly bounce between Lunar and Solar (current spreadsheet)
2) Stay in the current Eclipse long enough to cast SS three times, then rapidly go to the other Eclipse.
3) Stay above 50 energy. When Solar expires, proc it again.
4) Stay below -50 energy. When Lunar expires, proc it again.
A couple of weeks ago Starfox
reported those last two rotations are feasible.
For strategies 2 and 3, SF is used to extend Solar Eclipse.
For strategies 2 and 4, there are sub-strategies:
a) Use Wrath to extend Lunar Eclipse.
b) Use MF (with Lunar Shower*3) to extend Lunar Eclipse.
I don't think (b) is favorable with the current spreadsheet numbers until the Eclipse bonus is over 60%, but we should at least have some measure of its worth (or lack thereof).
Edit: Both Wowhead and MMO are showing E&M debuff at 13%, although I did see the earlier blue post that put it at 8% (and Ebon Plaguebringer is showing as 8% at both sites).
