Well if you are starting a brand new account, you do need gil. Silent oil, prism powder can be pretty high in price when first starting the game with absolutely nothing.
That was my take on how to get past maps fastest way possible. Also need some basic gear to play in Gusgen mines. And as WHM, RDM need to buy spells.
Gear and food contributes to how fast you can speed level up until you reach Abyssea.
My point of view was based on as if I start a brand new account how fast could I reach 99, skip a good portion of content and earn a delve weapon/gear.
I've never done skirmish too, just getting Orvail set allowed me to play delve easier.
