Let’s talk about the actual reality of being the "Warrior of Light":

The Point-A-to-Point-B Simulator: I spend 70% of my playtime running from one NPC to the next, only for NPC A to tell me to ask NPC B (who is standing literally 10 yards away) if he’s had breakfast yet. If I’m putting in the mileage of an Olympic marathon runner, I’d like to see some virtual rewards for it, thank you very much. Every quest turn-in is basically a receipt for my worn-out soles!

Assisted Living for Eorzea’s Elite: The helplessness of these NPCs is truly world-class. We literally save the universe, slay gods, and stare into the abyss of the void, but apparently, Alphinaud and the gang can’t even boil a pot of soup or gather information without me holding their hands. That EXP isn't a "learning experience"; it’s compensation for the emotional damage I suffer every time I have to "survey the local residents" because the guards apparently have collective amnesia.

The Human Statues: Has anyone actually considered the NPCs who have been standing in the exact same spot since the ARR era (2013!)? There’s a guy in the Waking Sands who has been waiting TEN YEARS for me to bring him three grapes. Is that dedication? Or just extreme laziness? These people have grown roots while I’m out there saving the world. When I finally show up to finish their menial tasks, EXP is the absolute bare minimum I can demand as "hazard pay for dealing with social incompetence."

Conclusion: As long as NPCs don't learn how to pick their own grapes or walk three steps forward without having a panic attack, that EXP is staying right where it belongs: in my bar.
