Need Before Greed

Need Before Greed describes a rule of looting etiquette as well as a deprecated loot setting enforcing that etiquitte.

While part of a party most players will expect that if they need an item they should get first pick at it before those who want it for Greed. For example, a party consisting of a rogue, a mage, and a warrior walk into a bar and loot some rare cloth armor. All of them can potentially wear that armor, but only the mage really needs it, the rest will likely just sell it or give it to an alt (see Greed). Therefore, it is expected that the warrior and rogue will allow the mage to have it by not rolling on the item.

Etiquette
It's not always obvious who needs an item, perhaps the mage already has better armor or perhaps the party loots some crafting items and it's not known who has what professions. Prior to patch 1.9, people would typically say "n" or "g" to indicate if they want an item for need or for greed. Now this declaration of need or greed is built into rolling for an item. If everyone declares greed, then everyone rolls for the item; if one or more people declare need, only they roll on the item, which is the usual tactic of ninjas.

Loot level
Prior to patch 8.0.1, there was a Need before Greed party loot setting which is an attempt to enforce the above etiquette. Those party members who can't use an item (such as mages and mail armor pieces) or who can't use the item most effectively (such as warriors and cloth armor pieces) aren't given the chance to loot an item until the party members who can most effectively use the item have the chance to loot it.

Problems with Need before Greed
Before patch 3.3.0, the Need before Greed setting only took into account whether or not you could use the item now, not in the future. This means that if a mob dropped a piece of armor requiring level 37, the level 36 warrior in the party would not be able to roll on it. Similarly, a level 39 hunter would not be able to roll on mail items even though they would be able to use them next level.

With patch 3.3.0, the Need Before Greed system was redesigned to recognize gear appropriate for a class:
 * 1) The class must be able to equip the item.
 * 2) The class must have a spec that uses the item's primary stat (strength, agility or intellect if one of these is present; stamina otherwise).
 * 3) Classes are limited to their dominant armor type (ex. paladins for plate).

For items other than equipment, other restrictions apply; you can't roll Need on:
 * Mounts or companions you already have.
 * Recipes you don't have the required professions for, including tradable recipes for items that you need.
 * Chaos Orb if you don't have at least 500 in a profession that uses it.

Anyone can roll Need on gems.

All items will still be available via Greed rolls (except for duplicate Unique items) as well as the new Disenchant option should no member be able to use the item. Low-level items are unrestricted.

Off Specs
As Hybrid classes (such as Druids, Shamans, and Paladins) and other classes capable of performing multiple roles (such as Warriors and Death Knights), items may drop that may be used for any of these roles; NOTE: This may not apply to Priests because they may or may not use the same gear for both healing and DPS. Many players have different perspectives on rolling for off-spec loot. Many players agree that gear rolls should be main spec only, which in most players' opinion, is the role that they are currently playing with, even if it is the player's Secondary spec. In a raid setting, it would be more beneficial to the raid if the active tank is allowed to roll for a tanking item over a Paladin or Warrior currently acting as a DPS.

If you are running an instance or raid with the intention of getting off-spec gear, or there's a chance that off-spec gear will drop, it's best to declare this before the run starts and make sure everyone is okay with it. To be absolutely polite you should be willing to forgo main spec Need rolls.
