Only because it’s been buffed by your DoTs. See how much damage it deals otherwise.
And what makes it deal that higher damage? The DoTs.
Let’s say I have a 1-minute GCD that deals 40% SP but increases my damage dealt by 20% for 20 seconds, while my Shadowbolt-equivalent is 140% SP. Do I not use the first because its damage is lower in itself?
Now, the same question, but for a 40% SP ability that increases your Shadowbolt-equivalent damage by 40% SP each for those 20 seconds in a situation? Do I not use the prior because its damage is lower in itself?
That latter spell hasn’t increased that damage on its own; it’s more useful to think of the first as contributing 40% SP per GCD for its GCD and each filler within its duration, rather than considering the otherwise neutered skill as the source of all that damage.
Tl;dr: You’re conflating a details entry with what actually gave it that bonus. There’s a reason warcraftlogs redirects that bonus back to the Priest/Augvoker.
I’m not the one misunderstanding this. You’re still missing why this isn’t merely a matter of “ramp-up” / why that conflates separate smaller and otherwise addressable factors.
If each DoT were solely a damage amplifier for Rapture, you’d have a point —just as having n uses of Colossus Smash would be inferior to a single Warbreaker— but they’re not. You instead have n uses per soft-CDs of, when at all accounting for their indirect contribution, your skills with the highest maximum damage-per-global. What limits them is simply what causes that potential to go to waste.
Nor is it even true that you should always set up every single DoT on every single target.
A Seed applying Corruption across 10 targets (example number chosen for obviousness of effect) will have already increased your Malefic Rapture damage by 380% SP per cast. The more additional time you spend applying DoTs to the extent of losing MR casts over the periods of densest application, the more you devalue (cause waste among) each previous DoT since they each generated 38% (or in Seed’s case, 38n%) less SP.
- One more DoT granting 38% more damage per each of 5 Malefic casts thereafter is not worth getting one fewer Malefic in while 10 simultaneously applied DoTs are running unless its base damage is worth more than 190% SP.
That’s not a ramp-issue so much as anti-synergy among high target counts that creates an especially soft (and Haste-dependent) effective target cap. One that, again, can be dealt with through additional effects regarding DoTs already placed and, especially, DoT duration that would otherwise go to waste.
Stop conflating the different loss factors as a single thing and voila, there are solutions aplenty without having to change Affliction’s playflow.
It would still have the limitations faced by, say, 5-cap-AoE DPS (making them shine more at higher Fortified keys with their smaller pulls than elsewhere) but their contribution per high-total-SP/gcd spells would be more assured.
