Isn't Stormblood supposed to have a full game worth of content? Maybe this also entails a full leveling of a class to 30, rather than just starting at 30, do forgive me if I am misunderstanding ( also typing with a broken keyboard is kind of hard lol). We could also have a new starting area too if that's the case. But again, this is prefaced with me maybe not understanding something (disclaimer). I mean redmage could be a job, but they could have "fencer" as a class and do what they did with sch/smn and have like... runefencer and then rdm?
another thing... but this would probably include a huge reworking of the system, I presume, but they could daul spec the class itself and have people be able to have a strong support rdm, or a dps rdm, or even tank rdm. But again that sounds like a lot of work. So that's more me getting really fanciful with my speculations lolol.
Even if the redmage is the jack of all trades, and that necessarily doesn't mean it will be such a class in the game, it would still be interesting to see how they would implement a classic (puns anyone? no?oh...). Like a few of you mentioned, a LOT of us who have played ffxi (myself included, I mained a RDM for a bit before switching to whm) are assuming it will be something similar to that when we really should give it a fair chance. FFXI and XIV are two different games, though I personally think they could include some sort of enfeebling or something
