What is the thought process with Warlord/Named Weapons?

Love this game, but I can't understand the thought process behind these named weapons. Caduceus is the only named where the talents enable a specific playstyle. The rest just sort of.... Suck? Midas is ACCEPTABLE because it's a set roll that enables SMG Healing. Other than that...

Warlord is an especially bizarre example. The gun reward for the most difficult PVE activity in the game is obviously inferior to any gun the player would use to beat the mode in the first place.

It doesn't have any unique talents that might make a new build possible. It doesn't have talents that synergize. It's just a mediocre gun with a unique skin that nobody at endgame in their right mind would use.

What could possibly have been the intent?
