Thanks everybody for their inputs! Sadly I can't try out shield swipe efficiency on a dummy, where I'm trying to get used to the new rotation. I'd assume it's a DPS loss since it takes a gcd which shortens the possibilities to re-appling the goring dot twice in the same pull. At the same time, Shield Swipe helps me to back-up my emnity generation and keeps me from doing an "oh-sh-" RoH because of the high DPS's emnity generation.

Alright, I've been running some tests, using STR gear (Shield Oath up) to make it more noticeable, excluding mentioning the off global cooldown skills as they are used the same way no matter what rotation I use as a filler between cds, but as soon as possible to have them available early in the fight again.

1st rotation: Shield Lob then FoF -> Goring + RoH + Royal / 2:51 min testing until I run out of TP: 518 ~ 540 dps.
2nd rotation: Shield Lob then FoF -> RoH + Goring + Royal / 2:50 min test until I run out of TP: 500 ~ 515 dps.

Shield Swipe might actually decrease these numbers as its potency of 210 is lower than RoH (260), Goring (540, if I'm not wrong) and Royal Authority (Sick 340). It don't know if TP wise would be an issue to have Shield Swipe as a ready-to-use whenever it procs, because I used to spam it back in the day to keep it up with the DPS and save some TP. Specially in fights like Bahamut, where you're hitting that winged fire breathing pinata for a whole bunch of minutes.

As an OT: Pretty straight forward. No hate rotation here. Just keeping Goring dot up and spamming Royal Authority puts me above 740 ~ 766 DPS sustained over 3 min until I run out of TP.

All these numbers without food, party buff, without pots. I don't know if these numbers are good since everybody is busy parsing both wars and drks.
