There is nothing easier in this game than getting gil. And it's never been easier than right now to get gil. It's easy^easy
A) Not everyone multi-boxes (like myself).
B) Not everyone who multi-boxes is very good at it. At least, good enough to solo (multi-boxing) things such as Dyna D, D+ Ambu...even some I know can't multi-box Vagary.
C) Not everyone who multi-boxes or does not is able to write a script whenever they want to farm sparks while they sleep.
So no, getting the amount of gil that it would require to get someone skilled to merc Lillith for you is not
that easy. Maybe easy for you, for me or for a skilled multi-boxer, but this fella said he can't even solo the BC on E. That doesn't sound like someone who can just farm up 200 mill+ for a few pieces of Malignance on a dime.
