Why is game entitlement a thing and people think they deserve every item in the game?

[Malzian]

What if they were one of THOSE people??? They joined a farm party, tanked the floor for the entire fight and got the birb that dropped?

In the same vein, what if they were in a progression party and they died and tanked the floor but their party cleared by some miracle and they got the [insert special rare drop here]? Do they still deserve it? New raids/EX primal rule: If you die during the fight you can't roll on loot! /sillycommentalert
