I don't remember if the 85 spirit regen number changed. I do know that we now have (at 85) 931 MP5 which is a class-and-level-dependent number that applies both in and out of combat (all Druid specs, in addition to spirit regen). So if you are trying to solve for BASE_REGEN, be sure to include that number (at 85).
Keep checking--there will probably be frequent changes, esp. since the Moonkin sheet is so much further ahead than Resto right now. Also, now that 4.0 is live and I'll be playing Resto in 25-man raids, I'll have a much better sense of what's going on.
I definitely will, but at least something to start (structure, etc). I can change formulas/numbers fast enough, if the structure of moonkin will be close to resto one - easier for me to make the moonkin calcs.
In order to obtain 6 ticks, you need haste values to acheive a time between tick duration to be (12 / 5.5). Ticks round up, but keep in mind that your hot duration can extend past the normal hot duration.
12 / 5.5 = 2.18181818
3 / 1.05 = 2.85714285714 (this is your hot ticks 5% raid haste)
2.85714285714 / 2.18181818 = 1.3095238106
30.95% haste from gear is needed to achieve this to bring your rejuv tick time to 2.181818 with raid haste.
30.95 x 32.79 = 1014.8505
So 1015 haste rating is required for 6 rejuv ticks and a ~13.09 duration rejuv is obtained.
This is a little off topic so my apologies if it is in the wrong forum. I was wondering if the darkmoon Greatness card was considered usable again by anyone? I was thinking about it today as at level 80 regen isn't a problem so were mainly gearing for haste then crit/mastery. It's 90 int with a proc thats 300 int (for us with int being our highest stat) and as I checked today it gave me ~276 spellpower and about 4-5k mana. Has anyone else considered it viable again? It was such a fun trinket in its day.
