T9 vs T10
Posted by thideras | Filed under Restoration
I’ve seen a ton of posts that claim they gain exorbitant amounts of healing from the T10 4 set bonus:
I ran the numbers when it was first released, and it was under T9′s 4 set bonus. I used a “test” environment (paper) to calculate these numbers. I assumed that I’m in a 100% Rejuvenation rolling strat, maximizing the throughput for each set and removing any other factors. So, let’s break this down to find out what is giving the numbers in the absolute best possible situation. I’ve made a lot of assumptions to assure this is a perfect scenario. We are in the midst of a Rejuvenation rolling fest and I’m going full out; 15 raiders always have my spell active. I’m so good that Rejuvenation never falls off anyone and it is refreshed the literal millisecond the buff falls off (no overlap). The fight is only 60 seconds long. My crit is 20% and spell power is 4000; these are fairly close to my actual stats in raid. Everyone is also grouped up so that my Rejuvenation “spawn” always targets a player that does not have Rejuvenation on them.
Going based off Norfair’s amazing post here, we know that Rejuvenation has a coefficient of 0.647 per tick. Meaning that 1 spell power increases the healing done of Rejuvenation (per tick) by 0.647. Rejuvenation has a base tick of 338.
Rejuvenation tick = 0.647 (coefficient) x 4000 (spell power) = 2588 (increase) + 388 (base) = 2976 (base) x 1.06 (ToL increase) = 3154
This means that Rejuvenation ticks for 3154 every 3 seconds. I’m rolling Rejuvenation on 15 people for 60 seconds, so we need to find out how many total ticks that is.
Total ticks = [15 (people) x 60 (seconds)] / 3 seconds (per tick) = 300 ticks for our test
Now that we know how many total ticks we have, we can figure out our total healing with each set and the complete HPS increase. Please note this is a perfect world, and thus, the numbers will be a bit higher than “normal” since there is no overheal.
Base healing (no tier) = 3154 (Rejuv tick) x 300 (ticks) = 946,200 healing
Base HPS (no tier) = 946,200 (healing) / 60 (seconds) = 15,770 HPS
T9 Calculations
We now need to calculate how many crits I would get from our T9 bonus and the total of healing throughput.
Rejuv crit = 300 (ticks) x 0.20 (crit chance) = 60
Normal healing = 240 (non crits) x 3145 (Rejuv tick) = 754,800 healing
Crit healing = [60 (crits) x 3145 (Rejuv tick)] x 1.5 (crit modifier) = 283,050 healing
Total healing = 754,800 (not crit) + 283,050 (crit) = 1,037,850 total T9 healing
T9 HPS = 1,037,850 (healing) / 60 (seconds) = 17,297 HPS
T10 Calculations
Moving onto the more fun calculations, T10. Crit is not a factor here, so it makes it slightly simpler. We need to find out how many Rejuvenation ticks will “spawn” a new one and factor their healing in as well. Again, I’m assuming that it jumps to a person who does not have Rejuvenation and it ticks for its full duration/power.
New Rejuvenations = 300 (ticks) x 0.02 (spawn chance) = 6 new spawns
Healing per Rejuv = 3154 (Rejuv tick) x 6 (ticks per Rejuv) = 18,924 healing
Base healing = 3154 (Rejuv tick) x 300 (ticks) = 946,200 healing
Total healing (T10) = 946,200 (base) + [18,924 (spawn) x 6 (total spawns)] = 1,059,744 healing
T10 HPS = 1,059,744 (healing) / 60 (seconds) = 17,662 HPS
Now let’s total these up to find out how it works!
Base HPS = 15,770 (+0 HPS)
T9 HPS = 17,297 (+1527 HPS)
T10 HPS = 17,662 (+1892 HPS)
Remember these are “fake” numbers, but they do show value. T10 is *an* upgrade, but not as much as people would like to think. This is assuming that no healing goes to waste.
What does this mean?
This means that anyone claims that T10 is “substantially better” than T9 is full of it. Yes, show your parses where you do so much better; they mean nothing. Looking at the overall picture, they should not be better. “But Thideras, I *did* do better than them!”. Congratulations! You’ve discovered “variables“. This means there is another portion of the fight that is not accounted for in my calculations. Skill, damage type, latency, healing style, etc. There are so many variables, there is absolutely no way for someone to calculate all the differences. I did these calculations the week the information was released about the 4 piece and I was not impressed. You know what? I’m still not impressed. I’ve been holding off getting my T10 piece so that other raiders can get their second tier tokens and I will continue to do so. The upgrade is minimal for me and actually frees up my gear choices substantially.
Now, don’t take my post incorrectly. You should still be going for T10, but it isn’t that big of an upgrade. As I just stated, I let others take upgrades before me and find other gear in the mean time. I still do extremely well on “the meters” and my targets don’t die.
