The Warrior of Light is a power fantasy player character if ever there was one. I see MINE as a character because, even if I do not RP, I made a whole personality and backstory for him. My imagination just abhors a vacuum.
It's too bad because I think the game would be more immersive if we could run into someone who genuinely hates the WoL. Right now a character poised to hate us is Lord Francel de Haillenarte (the character you save from being branded a heretic in 2.0.). We saved him but took his best friend away too and he's been finding excuses to not help us so far. Imagine if he shows up again raging at the WoL for the fact of their existence. It would be kind of amazing, wouldn't it?
That's really my problem. Nobody dislikes the WoL in lore. The WoL is incredibly powerful, too. The most immersed I have ever been in the WoL story was 2.55
When the WoL is a wanted criminal and doesn't even have their Light anymore. Sadly this was all undone in Heavensward. The Sultana is alive and we get our Light back.
Warrior of Darkness could be interesting to put pressure on the WoL but I would love, LOVE to just find someone who hates the WoL as a person, not because they're a villain and the WoL is good.
