if you need it, need it. if you don't but you fancy even just selling it, then greed it. It's totally fair enough.
If you mean YOU as the specific player then I agree.
It is fair what you write, but in most cases it does not work in reality nowdays.
There are to many that thinks their companion is equal need and players that seems to make up excuses why that specific item they canīt use is equal important to them.
A item that drops is a item that belongs to the one in the team that can equip it, very simple and very true. Anything else is a matter of communication and if the team agrees it is reasonable enough there should be no problem whatsoever.
