The thing is that BRD already has the numerically strongest raid buffs in the game right now. At full power, BRD has 6% dps + 20% dh + 2% crit buffs during burst while everyone else is 3-5% buff with AST likely being the second strongest (6% + 2X 6% single target buffs). And yet, BRD is the least played phys ranged even though it is currently the strongest in its role, but still one of the weaker dps jobs according to The Math™. However, the bulk of its damage comes from Burst Shot spam so the answer is potency.

The problem is that raid buffs, and buffs in general is that they are an inherently passive mechanic so any job in any role whose main focus is their raid buff will end up with a passive gameplay loop. Another inherently fatal flaw with raid buffs is that they are best used on, and used by the strongest jobs/players so you won't be uplifting the needy, but instead making the rich get richer. Which is my biggest gripe with DNC's design. That's not support. Which is why I generally believe that trying to make phys ranged a 'support' role is a flawed approach, and instead they should lean more into them being snipers/marksmen/ranger jobs that simply use ranged weapons to deal physical damage... from range.

I can kind see what they were trying to do with Finishing Move, where it seems like it's there to help mitigate Standard Step drift when everything lights up after using Flourish, but it's just a bit awkward because it removes the dancing mini game. I wonder if just letting Flourish reset the cooldown on Standard Step could achieve the same result.
