They're not adding any job related to dot archetypes. Every job has had their dots pruned down to 1 or none. BRD is the only exception and even then, I feel like they're getting ready to give their dots the chop.

Considering the entire debacle that is the debuff and buff limit that crops up every now and then (recently T.O.P. Ultimate), they would need to finish that before proceeding with any addition of dots.

It's kind of baffling how they've never seemed to properly address or fix the issue–just reducing the amount of dots we have to coast by. At some point they're gonna have to actual fix it, especially since they're keen on making fights with debuff mechanics.
