Ah yes Archanist. The class that always slips my mind. But the problem I see is bards wield instruments, there's no relation simply being guided by the armory system or should I scrap the idea because of the weapon? If my memory serves, Bard specializes in buff, debuff, enfeeble solo/aoe capability. Sounds like a relative to THM more than anything. But XI had Bards as pullers, so the idea on that level would trigger the thought of ARC, but still can't see it.

Again though, lol, this whole Job thing has nothing to aid us in our speculations.

Here is what "I" think:

PGL > MNK
GLA > PLD
MRD > WAR
ARC > ???
LNC > DRG
CON > WHM/BLM
THM > BRD

And why not:
ARC > RNG/SAM/THF

SAM might be pushing it, but XI has shown SAM's have a talent for bows. Speculate, speculate, speculate
