How to Dragoon per Second: A DPS Paradigm

[Sentinillia]

Is the advanced opener on the first page still good?
H -> [BL+BFB] -> ID -> [IR+BOTD] -> DI -> [DRAC-POT] -> CT -> [PS+ LEGS] -> 4TH -> [JUMP] -> P -> [SSD] -> TT -> [DFD] -> VP -> [LIFES + GK] -> FT -> 4TH -> Repeat

Short answer: Yes.

Longer answer: There are openers that are a little more optimized for opener DPS and you may have to adjust your opener slightly in a given encounter, but yes that opener still works mighty fine. If I recall correctly swapping IR and B4b in that opener gives you slightly more PPS since your B4b will extend to HT which is more potency than ID.
