The DFA playstyle wasn’t really even Dancing for the sake of openers anymore lol. It’s literally just the one GCD of DFA during the 4 seconds of damage buff that did everything. We want to maximize the rest of that 4 seconds, sure, but looking back, I’m honestly not even sure how much difference that would make. It was fun, but the focus wasn’t even on Dance at all, and saying that playstyle had “Dance uptime” is laughable.
And, regarding the direction of Sub in SL, I’m actually decently happy about what they’re doing, after playing the current Sub in a few 15 or higher keys. Right now, beyond just having no damage at all, Sub also has this issue where a whole bunch of our kit is useless in certain situations. For example, FW is a good debuff to have up, but in an AoE situation, applying it to anything beyond your priority target is just not worth it, since pumping out an Evisc every other GCD is better. Thus, on the average trash pull, you effectively lose a whole talent row’s worth of DPS, and the same thing sorta applies to the bonus damage on Nightblade as well. That bonus damage is basically Sanguinary Vein, but without Crimson Tempest to apply it, it’s also not used at all in AoE situations in favor of spamming more Eviscerates. Then, on single target, the Night Vengeance Azerite trait–which is completely core to our spec–also suffers from the same issue. You can do into SD with it up to immediately get off a big Evisc, but after you’re in Dance, it eats up CPs and GCDs that could’ve gone to Eviscerates, so trying to proc a damage buff actually ends up being a detriment to your damage.
What we want is a way to set up the debuffs, and then spam many upfront damage finishers back to back. High FW uptime + Shuriken Storm FW application gives us exactly that. It basically merges all our maintenance enemy debuffs into one easily-applied thing, and rewards us with basically the same thing–extra damage. With the right tuning, armor shred/percent damage increases/shadow damage procs will honestly all just be the same thing with cosmetic differences. This way, we get to use all of our kit, all the time. The only point of concern I see so far is Shadow Vault animation self-stunning us.
Regarding energy and wanting to pool energy, it’s gonna be hard to tell how that’s gonna go lol. So far, the trend has been us getting our energy sustain through the borrowed powers of each expac, with stuff like Energetic Stabbing/Lucid Dream Minor, and pretty much none of the Rogue borrowed powers are out yet. I want to be hopeful, but honestly, we’re basically mandated to be hopeful anyways, since we already can’t go any lower on the damage chart lol.
