Delve does not require a MNK with formless, Delve requires magic damage. There are many jobs which can fulfill this role. Take out a DD and put in a BLM give them Ballad and MAB Rolls, you will see them throwing down great nukes, Mata can be killed by SCHs, GEOs, RDM, and BLM, you should have 6 jobs at very least capable of throwing nukes at him for capped DMG with spells on a 10 second recast timer or lower, which should make him a joke, that's 23 nukes, split between 6 people. The thing is that no one takes a BLM, why? MNK can do it, why bother?
Question is, what are they fighting, if the target has less DEF than their attack by a large enough amount, that's why. Drakes will win most of the time if the target has quite a bit of DEF lower, which is why as an Upu DRG I always use Drakes in anything outside of Adoulin, my attack crushes everything DEF in old content.REM + REM WS = always better...
Just from what I've seen in my drg friends with their iLv spears... Drakesbane has been outperforming Stardiver constantly... Or at least it has every single time I have ever seen them use it.
I think its worse than PD really. PD was a 1 shot thing, once per event, Formless can be used multiple times and reset by CORs multiple times if need by, once by an ability with what I think is like a 20min recast, and the other is their SP. PD was at least a 1 shot wonder, you popped it then you just stunned. So far as making NMs that do not rely on PDT/MDT things, its not easy to come up with a gimmick to make the NM unique which does not rely on such a thing, or at least I have a hard time coming up with them.And you're right, the job isn't broken because of Delve... it's just that Delve severely caters to demanding MNKs due to the design of the NMs.
Alexander's PD was never really overpowered....
But the Devs kept making content that practically demanded its use.
They realized it, so they neutered PD to make it so they wouldn't make content that then relied on PD to be defeated...
And I think it's basically the same thing here: Delve has been made so that MNKs with Formless is the PD of yesteryear.
Though I don't think FS is as potent as PD...
I think to "fix" this... all they have to do is program NMs in the other 3-4 fractures to not rely on these MDT/PDT shenanigans that the current ones do.
