I've always loved Fight or Flight because I started the game before there was Holy Spirit. PLDs had FoF, DRKs had Blood Weapon, WARs had Berserk; each of these were strict damage increases for bursting, but felt very different and unique. Blood Weapon even used to have a haste effect. I love Holy Spirit too, and I love PLD's class fantasy and job identity of being a knight who uses both their sword and shield and Holy Spirit in their rotation. Having these two kinds of burst phases means there's not too much emphasis on either side, which is important to me. If Holy Spirit is the only burst, then it feels like your sword is worthless and that makes the job far less enjoyable on a core level to me. Now that Holy Spirit has the sword combo finishers, I was hoping in the next expansion they would work on improving the physical sword skills PLD has, upgrading them much like DRG got upgrades this expansion to their base rotation skills. So a different Fast Blade and Riot Blade; it probably wouldn't change the 123 Atonement rotation, but that's fine: I like it and largely why I enjoy PLD so much. I like the consistent of the 420 potency Royal Authority + 3 Atonements then the (previously) 420 potency Holy Spirits for consistent damage throughout the fight, with minor bursts with Fight or Flight and Holy Sword combo.
