Just out of curiosity, do you try to use macros for your oGCD skills? the macro system in ff 14 is pretty bad and doesn't "queue" skills so if you try to use them they can easily add a sec per skill to your reaction time. Admittedly im mostly just used to bard, but it can be pretty double oGCD heavy cuz of bloodletter and it seems to go well overall. When i used to use macros though it was considerably more sluggish and they would get clipped alot.

On the "more action" approach, I do not think it is the right move for FF 14. Legion for WoW imo has kinda moved to a arpg's pace of action and quite frankly i did not enjoy that change. And while i do enjoy BnS and BDO on their combat system, it is also something that works well there, but doesn't automatically mean it would transfer well. (and i do tend to find them tiresome on longer play sessions) To me FF 14's combat feels like an interesting take on the active time system ff games are known for, and I quite enjoy that. XD
