It took a while for eq to reach that point. It will happen in wow eventually too. Most people don't care because this prisoner's dilemma of a loot system hasn't burned them yet. The tank hit need on a boe green mail/plate? Sure. The warlock needed spirit pants? Whatever.
Give it time. A boe rare or epic will have someone hit need and ignore complaints. Or a soj or whatever will be needed by the casters and then you spot the winner not equipping it. Or an enchanter will need every single green+ item nobody hits need on to DE and leave none for greeders. It only takes an instance or two of being burned to realize that since all need and all greed do the same thing, hitting need on items that either everyone needs equally and/or you can just trade if someone wants to nbg, is the way to go.
The result will be a fair boe loot spread, the enc having to give the DE mat to the winners instead of just hoarding, and only cucks or sentimentals who think words matter over function left bitter.
I can't wait for need all to come over from eq.
