My hopes for 7.0 are:

1.) Time Mage (Caster DPS):
Would basically function as our replacement for a damage overtime caster since the role is now vacant due to SMN redesign. Would fit TIM rather nicely since they focus around time based Magic so they would be able to put 3-4 dots on the enemy and accelerate them to deal fast damage.

2.) Mystic Knight (Scouting DPS):
Would use a whipblade and have a rune on their offhand. Would have roots to mystic knights aesthetic from FFV and can have gameplay mechanics of rune knights like how FFXI approached the job.
