This can't make it to live. As others have said, I don't enjoy subscribing to doomposting, but this will kill every bit of motivation I have had to hardcore play the game and I have many peers that feel similarly. Under this system there would be genuinely no reason to play more than a tiny bit each day on your main unless you want your account's progression to go wider via leveling mules... which a large amount of players either have no need or desire.
This change will make all the most dedicated players log in for an hour and log out.
