The 4th Tank.

As much as I love BLU, it probably won't make an appearance in FFXIV no thanks to how it is setup to have a set number of abilities and traits on all classes.

easily implemented. Bluemage learns his "enemy skills" actions from the job quests at each level interval. It'd make an awesome tank. Aggro Combo could be Goblin Punch>Thrust Kick>Asuran Claws, OT/Debuff combo could be a ranged, mp based like Magic Hammer(MagicdefDown)>Acid Splash(PhydefDown)>Bomb Toss, then an aoe aggro combo Aquabreath>Electrocute>1000 Needles. Mighty Guard, White Wind, Vanish, all cool CoolDown potentials. Vampire Kiss could be a cool dot/Bloodbath hybrid, the possibilities for Bluemage are endless really.

aoe aggro combo Aquabreath>Electrocute>1000 Needles.

I just don't feel proper with the idea of a Blue Mage whose AoE isn't Detonate or a similar explosion. Not saying your wrong, just that I want to go boom all day in town.

You're right, drop 1000 needles for Detonate. I would've preferred to use Shadowflare for the big boom, but it's been taken.

It can really go much further than that. Give them an ability called "Learn" that will reduce the damage of the next ability he's hit with by 30% and give him 1 charge of that ability. When an ability is learned, the "Learn" icon switches to "Cast" (or something like that), much like the AST's Draw ability changes to using the card. You get 30s or so to send a scaled down version of that ability back.

That's in addition to permanent skills like Mighty Guard.
