Needing, Greeding, Passing question

[Keydah]

Need: Everyone that is doing the instance on a class listed on the item (above the level and below the item level) rolls a number between 1-100 on the item. These take priority over Greeds. Whoever gets the highest Need # gets the item, hands down.
Greed: Everyone in the party rolls a number between 1-100 on the item. If nobody rolls Need, then whoever had the highest Greed gets the item. If someone rolled Need, all Greeds are invalidated.

Greed doesn't guarantee the item, because it's "I want it" not "I need it." I'm quite fond of this system myself, besides the fact that I greed on things I want for glamour (healing glamour, while on a healing class that can Need on it, because glamour gear should be fair game) and I watch someone with an i130 headpiece Need on a i80 headpiece.

Need: Everyone that is doing the instance on a class listed on the item ...

Well, not exactly all listed on the item, since what's listed refers to who's allowed to wear it rather than who it's intended for. On the nicer gear set pieces, these will generally be one and the same, but there's some pink Aetherial gear that's good enough to be in a loot roll, but still has the same settings as its crafted equivalent. On some of this, gear intended for magic classes is listed as "All classes" because anyone is allowed to wear it. If, however, its stats are intended for casters, then only casters can roll Need for it. The same situation comes up with gear that lists tank classes as well as LNC/DRG, but for which it's either the tanks or LNC/DRG (most often the later) who can roll Need for it, based on what stats it has.
