The 8000 hour players might not even know what they themselves want anymore. Usually when they get to that point and they're submitting feedback requesting rather large changes, it's unlikely that they'll find much joy even if their requests are implemented exactly. They are burnt out with the game and that's not something that is fixed by making their grinds easier, adding a load more maps/weapons, or overhauling a system within the game.

When they've fallen out of love with the game, the best solution is to take a long break or just fully move on.
