You can argue for something they said they will not do all you want. I think we get farther asking for things that don't interfere with the development team's arcane grand designs.

It's relatively easy to see that they like this personal reward chest idea a lot, and people have been complaining for "add to treasure pool" since WoE placement chests, and it's been a no-dice the entire time.

When they're convinced of something like this, they're not going to change the "cause," as you'd put it, so you have to jump through hoops to make it "better."

(although your analogy is pretty bad because a lot of times in medicine, there's no treatment for the cause, or you don't know what it is, and you treat the symptoms and ride it out, just fyi)
