Level 80 was confirmed quite some time ago in an interview; no details on how the level caps will proceed from there. It was also confirmed at Vanafest that Yonin/Innin will not be available at all when NIN is used as a support job. Yonin/Innin for NIN and WHM's Afflatus "stances" were identified as staples for the jobs and will not carry over, similar to how DRG's Call Wyvern is exclusive. Certainly this is subject to change, but they seemed pretty adamant about it).

I'll be taking RDM up first with SCH up second. As far as RDM support jobs go, WHM is sitting at 41. Without Afflatus, /WHM offers very little of use in comparison to /SCH, and probably not enough to justify leveling it. BLM is currently at level 45; I'll finish soloing it later. SCH is 75 already, so no need to worry there. BLU is at 38 and NIN at 37. Since these are melee subs, and hardly priorities, I'm sure I'll get around to them later.
