The set seems to be working correctly now. I use it regularly and its performance roughly matches what happened before the IC patch launched and bugged it.
Original Post
Just a theory, but one that fits my observations
Patch Notes 2.0.3 on March 30: "Fixed an issue with the Valkyn Skoria set where it was unintentionally proccing multiple casts of Meteor within a single global cooldown. This was particularly noticable in Cyrodiil."
I'm pretty sure they bugged or intentionally nerfed this when trying to restrict the number of procs.
I believe the set was working correctly before the IC patch. Here are some screen shots taken after the nerf but before the IC. They reveal very consistent performances:
April 15: Proc every 9.5 seconds. 946 DPS
April 20: Proc every 10.1 seconds. 913 DPS
June 6: Proc every 9.1 seconds. 1098 DPS.
June 9: Proc every 6.8 seconds. 1370 DPS.
June 23: Proc every 10.8 seconds. 1133 DPS
June 24: Proc every 10.2 seconds. 1059 DPS
Bank it: every 10 seconds it procs and it's worth roughly 1000 DPS for my build.
Then the IC patch on August 30 came and ZoS claimed to reduce the damage by 25%. They did more than this. Something was wrong. Here are my post IC parses, with basically the same build, consistently revealing something very different than the claimed 25% nerf to damage:
September 10: Proc every 14 seconds. 515 DPS
September 13: Proc every 19.8 seconds. 352 DPS
September 20: Proc ever 39 seconds. 233 DPS.
September 30: No procs for 69 seconds. 0 DPS. (It's possible there was one proc for under 9000 damage).
October 3 [Templar build]: No procs for 123 seconds. 0 DPS. (There is 67772 damage uncounted for. Most of that is from my light attacks and blazing spear ground DoTs. It's possible there was one proc).
At this point, I had my Lich Crystal and Molag Kena options, so decided to discard Valkyn and be done with it. Then, thinking about doing Malestrom on my DK, decided to give it one more test just to make sure:
December 12: Procs every 41.3 seconds. DPS too low to register. (I looked through my combat log and found the individual procs such as this one here):
If all ZoS did was reduce the damage by 25% as they claimed to have done, then we should still see the same proc rate and a DPS around 750. That's not happening. So what did they do?
I think ZoS changed how the set checks for procs. Before the IC patch, I *think* the game checked every single DoT you put down on every target. Now, I only think it makes a single binary check. That is, it does a simple yes/no calculation to see if you have a DoT active, rather than actually caring how many you have. So if you had 20 DoTs on a multiple targets, it does not matter: you get a 4% chance to proc a meteor on the first target you registered a DoT on.
I believe this to be the case because my first simple tests revealed nothing was wrong with it. I got normal results like this:
But when I started putting multiple DoTs up, I'd get either no procs or a much lower rate:
It's only a theory, but it is consistent with ZoS's recent efforts at trying to streamline calculations. We have seen them reduce the number of ticks on certain abilities and the eligible targets for those ticks (without regard for the benefit of those ticks, incidentally).
Whatever they did, the set is utterly noncompetitive. If only Zenimax put half the thought and effort into gettting rid of AoE caps and the stupid zergblobs that are enabled by them as they did in removing deer and nerfing "reward" sets, maybe we'd see more diverse builds that didn't just stack spell damage and blob into a ball.
******Update:*******
Dedicated a run through Maelstrom Arena with this frustrating/bugged/nerfed thing and anyone who claims they are getting good results from simply has not paid attention to their parses before the IC release.
Here is a typical example of what Valkyn set will grant you:
169 DPS! On the bottom of the list, below structured entropy. This is a build that uses nothing but abilities dedicated to procing it.
After round 6 I got tired of wasting my time and dying so I took the set off. But I do have some interesting data for comparison with respect to the Nerieneth Lich set.
On my Sorcerer, who wore the Lich set and used skills that do not proc it (indeed my highest damaging ability was lightning flood), this is what I had after completing Round 6:
21,042,718 total damage. 1,787,114 damage from the Lich set. 8.5% of all damage.
On my Templar, who wore the Valkyn set and only used skill that could proc it, this is what I had after completing Round 6:
24,275,733 total damage. 516,464 damage from Valkyn. 2.1% of all damage.
So, wearing Valkyn will get you killed more (the more damage was from having to redo rounds after dying) and works far less effectively even if you dedicate your build around it when compared to another monster set that does not require such customization.
