Shit, if anything rolling for glamour represents a HIGHER level of Need than gearing up. When I roll for off-class jewelry, for instance, that stuff gets turned in for seals or converted to materia the moment a higher ilevel piece falls into my inventory. When I roll a good glamour piece though, that gear is going in my retainer and staying there for potentially YEARS. (Hello, i70 Darklight pieces)

Not that I'd advocate that people not be allowed to roll Need for gear upgrades. Because that'd be pretty petty, wouldn't it?
