What makes it unfair to them is their lack of social skills, leading them not have friends or guidlies who pass loot to them and therefor everyone else is better off. So they attack everyone else, rather than fixing their own issues. Which is reoccurring theme with op. At least that would be my analysis of them.
Oh I will add that when they don’t have the lower ilvl, they would be left out.
It basically comes down to greed, they always want a chance over others, at the loot, no matter the circumstances.
Edit 2; Which they already had when the loot first dropped. So really they want a second chance at loot. Rng is the favored option of the lazy and greedy. They don’t have to be deserving, they can be dead the entire fight, they don’t have to put in any effort other /roll etc. The list goes on and on.
