The PTR was updated with build 9684 last night and it included a couple of the T8 set bonuses. Luckily for us the Druid Balance Set is one of them.
Item - Druid T8 Balance 2P Bonus -- Increases the bonus granted by Eclipse for Starfire and Wrath by 6%.My first impression is that they are underwhelming.
Item - Druid T8 Balance 4P Bonus -- Each time your Insect Swarm deals damage, you have a chance to make your next Starfire cast within until cancelled instant.
Obviously we can't really evaluate the 4 piece set bonus until we know the proc rate and if it has any type of internal cooldown. Though I will say that it needs to proc quite often to be valuable.
The 2 piece set bonus can be theorycrafted and now that I have done a little math I find it very underwhelming.
1. First I am applying the bonus in an additive fashion (0.30 + 0.06 = 0.36) to give it the most potential.
2. I'm assuming a well geared, fully buffed moonkin with 2900 spell power, 100% hit chance, 45% crit chance in T7, and 16.5% haste from gear (29.8% total with full buffs).
3. I am also assuming the changes to Natures Grace and Eclipse go live.
4. I'm only going to detail Starfire, but I will give you the results for my Wrath analysis also.
I talked a little in my last post about how to calculate the up time of Natures Grace. Since this is so important to calculating average cast times I will say it again. Since you can start 2 Starfire casts in the 3 second buff we want to see what the probability is that we will reapply the Natures Grace buff in those two casts. The formula for that is:
SF NG Up Time = 1 - (1 - Crit Chance)2So to calculate Starfire's average cast time we can say:
SF NG Up Time = 1 - (1 - 0.45-0.03)2 = 72.96%
- the extra 0.03 is from Imp IS
Avg SF Cast Time = (3/(1+Haste)) * (1-Up Time) + (3/((1+Haste)*1.2)) * (Up Time)
Avg SF Cast Time = (3/(1+0.298)) * (1-0.7296) + (3/((1+0.298)*1.2)) * (0.7296)
Avg SF Cast Time = (2.3117) * (0.2704) + (1.9264) * (0.7296) = 2.0306 seconds
So to calculate Starfire's average damage we go back to the formula:
Avg Non-Crit SF = (((1285 + (2900 * 1.20))) * 1.1) * 1.0712 = 5614.69
Avg SF Crit = ((((1285 + (2900 * 1.20))) * 1.1) * 1.0712 ) * 2.09) = 11734.71
Avg SF DPS = ((5614.69* (1 - 0.45-0.03)) + (11734.71* (0.45 + 0.03)) / 2.0306 = 4211.71 DPSWith Eclipse the Starfire looks like this:
Eclipse SF NG Up Time = 1 - (1 - 0.75-0.03)2 = 95.16%Now that we have set the base lets look to see what happens if we flip the 4T7 and 2T8 set bonuses, by reducing the crit chance by 5% but increasing the Eclipse bonus by 6%.
Avg Eclipse SF Cast Time = (2.3117) * (0.0484) + (1.9264) * (0.9516) = 1.9450 seconds
Avg Eclipse SF DPS = ((5614.69* (1 - 0.75-0.03)) + (11734.71* (0.75 + 0.03)) / 1.9450 = 5341.03 DPS
A normal Starfire cast with 2T8 set bonus will look like this:
2T8 SF NG Up Time = 1 - (1 - 0.40-0.03)2 = 67.51%An Eclipsed Starfire cast will look like:
Avg 2T8 SF Cast Time = (2.3117) * (0.3246) + (1.9264) * (0.6751) = 2.0509 seconds
Avg 2T8 SF DPS = ((5614.69* (1 - 0.40-0.03)) + (11734.71* (0.40 + 0.03)) / 2.0509 = 4020.84 DPS
2T8 Eclipse SF NG Up Time = 1 - (1 - 0.76-0.03)2 = 95.59%Summary:
Avg 2T8 Eclipse SF Cast Time = (2.3117) * (0.0441) + (1.9264) * (0.9559) = 1.9434 seconds
Avg 2T8 Eclipse SF DPS = ((5614.69* (1 - 0.76-0.03)) + (11734.71* (0.76 + 0.03)) / 1.9434 = 5376.92 DPS
Wow, that is a lot of math
What this boils down to is that dropping the 4T7 set bonus of 5% crit results in a 4.5319% DPS nerf to our normal Starfire casts ((4020.84 - 4211.71)/4211.71 = -4.5319%) .
Picking up the 2T8 set bonus of an additional 6% to Eclipse results in a 0.6720% buff on are Eclipse Starfire casts ((5376.92 - 5341.03 )/5341.03 = 0.6720%).
I've run these numbers for Wrath as well and they are comparable if not a little worse. Basically, since Eclipse lasts 15 seconds and there is about 35 seconds between Eclipse procs, we are getting a 0.672% buff to about 40% of our casts but a 4.5319% nerf to the other 60%. This is a net loss.
If this set bonus goes forward as is then we will see a repeat of the transition from T5 to T6 where most moonkin stuck with the T5 set bonus until they had 4 pieces of T6. In fact, depending on how good the the 4T8 bonus is you may see moonkin skip T8 all together.
I've tried several different values to see what what value is needed to make this set bonus at least comparable to the T7 bonuses. In my opinion, the set bonus would need to be increased to at least 15%, meaning Eclipse increases your Starfire crit chance by 45% instead of 30%. A this level the Starfire Eclipses would do about 6.6% more dps then they would do with the 4T7 bonus. For Wrath the buff would be about 5.7%. In the meantime, our non-eclipse casts would still be receiving the 4.5319% nerf. So, 15% is where I think it starts to balance out.
Other Changes New and Old:
Celestial Focus now reduces the pushback suffered from damaging attacks while casting Starfire, Hibernate and Hurricane by 23/46/70% and increases your total spell haste by 1/2/3%. - (Switches Hurricane for Cyclone)
This makes sense since Cyclone is already affected by Natures Focus in the restoration tree, and Hurricane could use some pushback resistance.
[Idol of the Shooting Star] Will be purchase about with 25 Emblems of Valor.I missed this, but a reader Epidemais sent me an email saying it is true. I haven't verified it on the PTR but I expect that it is true. Ghostcrawler has said many times that they don't like having Idols drop from bosses because there are generally few people in the raid that can use them. It doesn't have an impact on me personally since I was fairly lucky and one dropped in the first few weeks of raiding Naxx. However, I know there are other moonkin out there that have had extremely bad luck and they must be doing a /dance right now.
