Been forced to need on stuff, for about the entire lifetime of being with this game. Moreso now, with the expensies of the reputation system. (Consumables and commodities need EC...) One time, I was in a group that did greed on everything, and promptly the next instance pugged, need showed back up 'all' too quickly.
Just hit need when pugging, get some loot part of the time, sell it, move on. It's all pixels anyway.
