Yeah fuck Red Mage, give Scholar everything.
This ^. RDM is just fine outside of Abyssea. Old school events I would much prefer a RDM over a whm, rdm has their use in voidwatch too and maybe future end game events due to support. C4 is just fine for curing, 550 hp with good cure potency build (40%ish) is two cures to cap most DD Hp, maybe 3. They don't need cure5.
They could just give RDM Cure V when in Abyssea.
I'd be fine with an atma that gave +50% cure potency so I can just jack myself with FastCast gear.
Spoiler: show
WHM outperforms a rdm as a main healer in every way really, you just can't compare the two. CureV is still a major asset outside abyssea, not to mention higher tier curagas.
No they don't. For example: Salvage. I would rather have a RDM nuking and speeding up the kills than a WHM that is gonna just sit there. Sky, sea, ZNM, VNM, almost all of the old stuff is better off with a RDM main healer than a WHM. That's besides the point though, RDM aren't suppose to be main healers anyway which is also why they don't need cure5.
Eh~! I think you're overestimating the importance of RDM's advantages. RDM's niche has disappeared because alternative sources of Refresh (and Refresh being subbable) have outdated them. They don't have a supporting role to play in any but the most extreme fights.
Like, level 75: RDM has Convert, Refresh, and 2MP/tick in gear, which makes them the most MP efficient healer.
Now at 90: Other mages that want it badly enough have Convert, Refresh, and 5 MP/tick in gear (body-2, head-1, legs-1, weapon-1).
So! Can a WHM/RDM at level 90 do the same events that a RDM/WHM could do at 75? Sure, and they can do it better. All old content where you would have had a RDM/WHM, now a WHM/RDM can do the same job with the added bonus of Cure V and Cureskin. Can the RDM nuke and speed up the fight by 30 seconds? Yeah, most of the time on old content. But SCH/WHM could also main-heal most of old content these days.
Their niche is now high-stress fights where you care about the difference between tier 1/2 enfeebles and need the small amount of extra MP they provide.
This discussion wasn't about Scholar though. It was about why RDM doesn't need C5 and whm vs rdm healing. Also I would rather the utility of para/slow2/dia3/quick access to nuke/cure from a RDM than scholar having to swap arts and wait on strats.
The easier the content (i.e. older content) the more non-WHM will excel. Remember that healers are only good insofar as they allow you to survive. If you have that covered, you're better off looking for members that will speed up the fight. Consequently, it's kind of obvious that RDM will excel towards older content.
The issue you need to consider is that, stepping forward, the content might change to favor healers that can cure more HP per cast. Not to mention the reduced enmity (Two-fold; both per cure and in number of cures). It should be painfully obvious that SE makes events revolve around class properties rather than the other way around based on the trigger system and types of updates SE has refused to implement. Given that understanding, you should look to see how a class stands in a diverse range of events rather than current events.
A whm still has survival advantages for older content. You could say cleave big groups in salvage with a WHM, that you probably couldn't as a rdm healer(big gear pulls etc.). I'm pretty sure a rdm wouldn't be able to handle a full hasso war on some older content, and a whm would have little trouble doing so.
RDM nuking and speeding up salvage kills in the old days was great.
But now when you have super overpowered melees, does it really matter that much? Not really. Nice? Sure, but nowhere near as useful as it was at 75.
RDM's grand comeback will be through Enfeebles, not Cures or even MP Efficiency (Which used to be their main selling point). I believe that I read in the Manifesto that they want to make Enfeebles more relevant. They want to make it so they can actually land on an HNM, and they want to make RDM versions of them superior in all ways much like a WHM's Cures or a BLM's nukes. To pull it off right, they need to scale up mob difficulty while they're at it. If Voidwatch is any indication, then they are certainly on the right path.
That becomes problematic when you look at overall balance. If you make mobs that need enfeebles of RDM tier, you return to the cycle of needing particular classes to defeat mobs. If enfeebles simply make it easier, RDM becomes similar to the pre-Abyssea PLD, where only bad shells will opt to use RDM over other classes.
