How fast is fast?

[Daemon]

This is the method I would do it.

Job Thief
Starting from level 1-10 outside of Windurst. Do Gov Pages, earn enough conquest points to buy emperor band. Head to outer Horontoro ruins. Earn fire crystals, Wild onions to sell and earn gil for gear.

From level 10, but stack of prism powder, silent oil, heading to Gusgen Mines, leveling from 10-35. Grabbing all telepoints for DEM, Holla, Mea.
Farm subjob quest items and complete quest.

Walk to Jeuno, save Homepoint, do chocobo quest. Activate Abbysea, grab La Theine Plateu Maw.
Farm items for gil back at windy by using GoV tabs to return to Homepoint.

Change jobs to WHM,
level 1-10 off GoV pages outside windy, head to gusgen mines til 10-35. Stop.

Change jobs to Redmage, Level 1-10 outside windurst using Gov tabs. Head to gusgen mines level from 10-35.

Switch back to WHM grab VW stone, head to abbysea, enter party as keyer. Open boxes by chance until enough Cruor is earned to buy keys. Stay til level limit break quest. Stop. Do level break Quest, Join KI only abbysea groups to earn proper atmas.

Return to Abby as Thief level til limit break, stop.

After breaking each quest. Return and level to 99 on each 3 jobs stop.

Complete Adoulin Quest, buy -Pdt staff, farm dark rings, buy -Pdt cape, 99 AH gear head to Adoulin. Buy spells needed.
Skill up max skill with AH Food.

Playing as WHM, earn Bayld buy Orvail set. Stop.

Enter Plasm farming party with LS friends, Join Delve farm party / Ki party as WHM/RDM.

At this point I wonder how long this would take without earning any AF3 pieces and getting by on AH/Delve gear?

The point is not whether or not people need to gain gear from abbysea but how long would it take a pro to reach 99, enter delve and earn a delve weapon skipping all other content?

Although there may be some flaws, the point was to see if its possible. How much time do you guys think this would take? 1 month?
