As much as fun this sounds I reather not do this anymore.

Yoshi-P stated months ago that new Jobs will have more serious effects on classes than current jobs once thy are released

such as the example with GLA advancing into Dark Knight Yoshi-P uses everytime he discuss future 2nd Jobs, it does not confirm if GLA will get Dark Knight but YoshiP likes using this a example a lot, being that if GLA advance into Dark knight for a DPS job some of GLA skills will be adjusted or changed to suit Dark Knight's DPS role such as GLA tank combo still will have enmity effct removed or replaced with a new DPS like effect while having the combo potency buffed.

A much larger change will be Flash skill (AoE Enmity gaining skill) being replaced with Darkness (AoE Damage dealing skill)

Yoshi-P also mentioned that he does have some plans for some future jobs to require past Jobs such as Red Mage may require BLM and WHM lvl 50 quest to be completed first before you can unlock Red Mage or the Class that goes into Red Mage.
