I never understand the needing on an item, which you can't use?! Especially, when there is someone else in the group who could use this item. People are only thinking about themselves in the end it seems like it. I never pressed "need" on an item (not even a BOE) if it doesn't upgrade my current gear.
Where's the community by helping each other ( press greed on an item someone needs for example) and reach max level together? English is not my native language and I was looking for word to describe these people. the word I found; self-centered. and narcissistic :p
