soo, honestly,I didnt read all of the thread so dont know if someone stated something like this before^^.
First, - and I can be really wrong with this one- but i think i remember correctly, that yoshi said something, even bevore heavensward came out, in some Interview on possible new jobs for the hw expansion, that if someday redmage would come, it wouldnt be in a way it was used to ( again, it was a long time ago and i dont have the exact statement as evidence or something so I may be wrong), so if the redmage was some kind of jack of all trades, or a mix of white and blackmage, i doubt that it would be something like that again
second, my opinion on how the redmage would fit in is somesort of spellfencer, simply a melee dd with a rapier or maybe even a sword , who could buff the party with enspells ( and heard something like a significant move " double cast/ spell, remember that spell too, so you could use that to use 2 enspells at the same time once in a while).
so in the end we may got 2 melees with higher dmg , 2 melees 2 with a bit less dmg and more support ( for that , ninja would be pushed even further into the support role it already has the most of the current melee dds and drg would be pushed more into higher dmg), 2 magic ranges and 2 physical ranges with support
I dont know how you all would think of this idea but I think this fits great and would love to see this happening :3
Edit: and lorewise, I read something similiar already in this thread, dont remember who exactly , but it could really be something like if they're more of the melee typs of fighting in ala mhigo, like monk ( and maybe samu :D) then they could've said something like " why the hell are you standing there behind us, casting some fancy stuff, were in a bloddy war, take this sword and get your ass to the front , defending our country with your life/ body! " :D
