Issue is that even though the MSQ must be apparently experienced in chunks according to what we know about NG+, many of those chunks are little more than drip feeds of dialogue that can be spammed through. EXP is one thing but Gil on top of that? Yeah, no that's just asking for the botters to turn their attention to NG+ to run their programs. I could see them adding a title or mount at the end of the NG+ grind, kinda like how getting all Trusts back up to 80 provides a title for your hassle, but beyond that and you're just asking for too much trouble.
