Hmm... Guess I'm just oldschool in thinking here that you only Need if it is an improvement for the class you're playing at the moment.

If it's for vanity or "just because I want it" you should Greed so that everyone has their fair chance of getting it for vanity/just because while if there's someone gets an actual progression for the work they did can get that chance.

I have always felt that the reason why Need is only made available when it's for something you yourself can wear (and not what one of your alt classes can wear) is because Need was set there because it's if you actually need it.

Hate to say it but you don't need vanity gear, you want it. And this is coming from someone who loves vanity gear and being able to customize their characters to look a certain way. Whereas this game does make it so that you do need that +3 to your stats because of the way the Duty Finder's implemented and the required iLVL for things.
