The fact that you have to ask this question says enough. How many levels of selfish do you have to be to need on something for your companion that would be an upgrade for one of the players in your group?
How selfish do you need to be to assume you deserve loot because it happens to be for your character's class instead of rolling against someone else who will use their companion (and therefore be an upgrade to the player
) in 99% of the game?
The game isn't all about endgame anymore, and companions are useful to players who use them.
