How do i?

[Starlord]

1. Not everyone likes leveling everything and is actually the last thing you'd realistically want to try to sell someone on staying because that admits a lack of things to do :x
2. Have you? According to the forums no one does End-game. (Not joking either, whenever someone brings up coil as an end point for content people say only a handful actually do it.)
3. Do you? (Not sure what this point is..? Full i90 means either grinding for months or spamming the hell out of coil..aka more grinding which can turn some people off if it's pretty bad.)
4. What does obtaining millions of gil have to do...with anything? I don't unlock content by having millions of gil xD.

Something to do is something to do. Whether it's something you like to do is up to the person in question.

There IS plenty to do in the game, there are somethings that aren't his taste which is fine.
