Not sure if anyone has asked about this before, but I searched the forum with keywords "let us pass after greed" and nothing relevant came up.
Is it possible for the system to be made so that the "pass" button is always available even after we already pushed the button "need" or "greed"?
Scenario 1:
I hit greed on some dungeon drop (because sometimes everyone passes and the item would go to waste, so I usually greed everything just so it won't be thrown away when I could exchange it for Grand Company seals) and then a friend said "Oh I want it for my XYZ job, please" and their greed roll happened to be lower than mine. So I won it when I could have passed for someone who needs it more.
Sad panda.
Scenario 2:
I was stupid and half-asleep and hit greed on an armor that dropped in Syrcus Tower when I was actually aiming to get Sands of Time from later bosses. Not everyone hit pass immediately, so there was a few seconds for me to realize my mistake and could have passed before I received the item. However, the "pass" button was no longer available.
Again, sad panda.
Therefore, I truly hope that the "pass" button is available all the time until the treasure is distributed.
