I was a BRD main for Stormblood and cleared O12S with it as well as progging UWU. I love the job back then. I play more casually now and wanted to try something different, but now I am leveling BRD and it feels a lot less busy than I remember.

In regards to the mobility tax, I remember most fights during savage and prog, I was stacked with the group, unmoving. If you were too far away you'd miss healing, and there were only a handful of mechanics I remember that you could actually bait to make the phys ranged jobs actually feel like they were there for a reason.

I do think the mobility tax is too high. I agree that there should be some tax, but not to the extent it currently is. Also SMN is the most mobile caster but does much more damage than p ranged, and is either equal to or better than RDM at this point. So they aren't even all that consistent when it comes to the mobility tax.
