The tears are so delicious.
Also, there is not a single offline FF where you actually lose experience points for dying (individually), but nice job trying to twist things to justify a dumb idea. Falling behind due to your party killing the enemy while you're dead is different than actually losing points.
Do you know why FFXI had an experience points penalty? It wasn't because the developers followed your FF line of thought. It was because EQ1, the game it was pretty much made after, did.
I'm honestly surprised you didn't ask for all progress to be rerolled back to the last time you touched an Aetheryte if your entire party dies. It's the FF game over, amirite?
