Theorycrafting the rotation I listed
here using these numbers. (Of course, this doesn't account for the unspecified "adjustments" to Spike and Caltrop's DPS, but it does say something about they SHOULD be.)
Note: Scaling up the damage of Chemical Bomb by 25% to match its increased duration.
Note: I'm throwing in Lightning Fury (even though I'm using numbers from 46/20 above and 51/13/2 for LF, yes it's sloppy) as one GCD filler. It has DPGCD of 1.0k in my testing.
(Aside, LF has the same DPGCD as a full Shrap x5 > Det rotation, so its at least as good [actually better] use of GCD to use LF than Shrap > Det. If Frag can detonate Splinter, then that would be a better option.) All of these assumptions are generous to Sab, so the actual DPS will be lower than claimed.
Background:
On PTS right now, this rotation:
TB > FB > CB > Shrap x5 > Det > Caltrop x5 > Det >
TB > FB > CB > Shrap x5 > Det > Spike x5 > AB
Sustains 4.45k DPS on 3 targets, or 1.48k DPS per target.
PTS Changes:
TB > FB > CB > Caltrop x5 > Det > LF
TB > FB > CB > Caltrop x5 > Det > LF
TB > FB > CB > Spike x5 > AB > LF
DPS per target ~= (3 * 2.1 + 3 * 2.05 + 3 * 1.71 + 12 * 1.3k + 6 * 1.88k + 3 * 1.0k) / 30 = 1.58k
So in this case the changes are not a big DPS gain. This is kind of obvious in hindsight because we have basically traded some Shrapnel detonations for Caltrop. The DPS difference between Shrapnel and Caltrop isn't too significant, so the real DPS gain is from adding in more bombs -- but since we've only increased their share of GCDs from 20% to 30%, it's not enough. So buffing Caltrop by shortening the bleed isn't a significant DPS increase, because
the real limitation on DPS is Annihilation Bomb.
What if...
So what if AB's cooldown was 10 secs, then this rotation:
TB > FB > CB > Spike x5 > AB > LF
DPS per target ~= (2.1 + 2.05 + 1.71 + 6 * 1.88k + 1.0k) / 10 = 1.81k
That's a bit better! This equaties to 1.81 * 3 = 5.41k DPS on 3 targets, which leaves it 12% behind Stormcaller.
...wait, this is still pretty crappy. What's going on?
Well, it's obvious. SC/pyro is pulling 6200 on 3 targets, meaning it averages ~2k per target. But even Sab's best charge on a 25 second cooldown is below this -- Spike x5 / AB tops out at 1.88k DPGCD. The only things that come close are TB and FB, which are effectively on 8 and 10 sec cooldowns respectively and rely on properly spacing HE. (In fact, I've been pretty generous using the TB/FB numbers because HE is clipped from TB on the next rotation.)
Conclusions: - The damage of Sab abilities is overall just bad. The only skills that compete with Stormcaller's sustained DPS are two bombs that are restricted to 15-20% of the GCDs in any rotation. Even the peak damage of Sab -- currently on a 25 sec CD -- is worse than what Stormcaller sustains.
- Charges need a big DPS buff overall since they constitute the majority of GCDs in any rotation. Caltrop and Spike better be getting a substantial DPS buff in the next round of patches, or Sab is going to still lag far behind Stormcaller. Shortening the bleeds really doesn't do anything. (Contrary to what I thought previously.)
- Spike is too much better than the other charges. The other charges are kind of embarrassing -- they need to brought up so that Annihilation Bomb isn't as significant as it is currently. Even after Spike is buffed, Blast, Caltrop, and Shrapnel need even bigger buffs to smooth out the rotation.
- Once charges are brought into line with Stormcaller, Bombs will need another buff or there will be no reason to use them in a rotation. (They are currently lower DPGCD than Stormcaller sustains by themselves.)
- 10 second rotations are still awkward. We want to use 10-seconds because the bleeds (especially Spike) are much higher DPS, but we need to use bombs within these 10 seconds because they are much higher DPGCD. Only having 3 bombs, that leaves us with an empty GCD and nothing useful to use it for (in AE). Combined Arms should affect Splinter and Ember charge as well, and maybe Shrapnel instead of Spike.
This paints a pretty grim picture, and frankly not one that can be addressed by the patch notes Ailion has just posted. A new mechanic needs to be added or there need to be across-the-board DPS gains or Sab simply will not catch Stormcaller.
