Colour Me Blue - Blue Mage
Although no mention has been made as to whether Blue Mage (BLU) will eventually be implemented. It does seem like an obvious job for a future expansion that will inevitably appear.
With that in mind, I wonder. How can BLU be implemented into FFXIV and still stay true to it's image? The acquisition of new abilities and it's role in the party being the biggest conundrum.
The extensive history of FF has shown us that BLU acquires new abilities by battling monsters in the field and learning/copying their abilities. However in FFXIV the ability acquisition system does not allow for this. Perhaps BLU job quests could therefore be similar to that of the SMN's Austerities trials. Where the BLU would have to battle a special monster in a trial/duty and acquire a unique ability from them. Which would certainly be a fun and interesting quest line that works with the mechanics of the game.
However since BLU has such a unique set of abilities and lore, there are no real options for it to build off a base class. Most likely the implementation of BLU, much like DRK, MCH, and AST would again need to be via a job that starts at lvl 30, with no base class.
Not only that, but BLU is a very flexible job. The abilities it acquires from enemies have a vast rage of uses (DPS, DoT, Healing, Buffs/Debuffs) meaning BLU could actually be successfully implemented as any of the 3 job types (Tank, Healer, DPS) or a hybrid of these.
I will be very interested to see how the dev team tackles BLU in the future. I also wonder how the rest of you feel BLU should be implemented.
