Red Mage could use some help.

Welcome to BLM, friend.

And it's simple: RDM is the "jack of all trades" job in every FF game ever. One could argue that Verflare/Verholy are ALREADY stronger than anything the job should ever have had.

Yep. I don't even think anything else needs to be said about it. You said yourself it is capable of doing the content, it just isn't insanely strong like SMN, but coupled with its simplicity and utility (yes Embolden could use a buff to include magic damage just like I said before), there is nothing wrong with it being the weakest caster job.

Also, losing damage by using Vercure isn't really bad design, it's a perfect niche. What other DPS jobs can do that? None. The ability to save the raid by using 2-3 heal GCDs and netting a marginal potency loss is significantly impressive for a DPS job to have, regardless of rez dispensing ability.
