There needs to be a Priority Need system

The problem with saying "They can need it for their desyn" is, when do you draw the line? The only reason people can't need on every single thing to desyn is because of class restrictions, and I'm sure as hell that the developers didn't have the foresight to see this being a problem when they incorporated desynthesis in the first place (along side other updates in 2.3 such as the hunt.) I've seen worse reasons for people needing on equipment that isn't an upgrade, even as little as GC seals (and we're talking level 20-30 dungeons here, its worth less than a FATE or supply).

That is just how the system in this game works. Embrace it with all you got and stop been a baby because u lose a need roll.

I agree that this is a problem. People do "need" for greed.
people often forget the spirit of what the buttons are originally meant for.
Need is for a gear upgrade for whatever you're currently running the dungeon as.
Greed is not needing it, but wanting it for money/other purposes.

Even for Vanity gear i will only greed things, especially if someone else could actually use it as an upgrade.
I have no respect for anyone who Needs on gear that could be an upgrade for someone else when it is not an upgrade for yourself.
