Personally I don't think they will touch red mage at all. Red mage has traditionally never been good at any job. We have WHM for healing, BLM for magic damage, SCH for healing, AST being the hybrid. The boat already sailed for red mage during heavensward if you ask me. Red mage as a tank? Sure a great idea in theory, but this game places no emphasis on elemental resistance. En-spells would end up being much like flash. I have a hard time seeing where it would fit anywhere without it treading on too much of another job. Some have also mentioned giving red mage double cast, another great ability in theory, but they would say they can't add it due tor balance issues. If they did somehow add it, it would last maybe 10 seconds with a 5 minute cooldown. I can't see how they give red mage much offensive magic given how most of the other mage jobs have each elemental covered. The idea of parry being for red mage would end up as red mage looking much like paladin.
--- We can also discuss Phalanx, Refresh, any of the abilities from 11 if you want, but do you think they will give them any meaningful times they would last? We get an auto refresh now and in my opinion Phalanx would be too far outside of their comfort zone (and if the player base somehow did convince them to add this ability, it would again only last a pitiful time such as 8-10 seconds in the name of that balance!!)
I wish someone would sit down and write out how they think red mage would work without it treading on another job so much that we have two of the same jobs. Sit and think about it and I bet very few will come up with a working job for red mage
To be honest, I see them adding one DPS, MAYBE two. The two DPS being either Samurai or Puppetmaster. Puppetmaster would fit nicely into the lore since Ala Mhigo is the home of monks (if we are headed there). They could be an off branch of the monk tribe. Just my two thoughts. I'll be waiting for the detailed write up on red mage instead of saying someone wants it to complete the trinity even if it stomps all over an existing job.
