While you were told to simply dont spam Long Rests if you dont like it ... and as far as i know, you repeatly dismiss that as a stupid argument ...
Because that's what it is.
Serving to the players unlimited convenience on a plate and then asking them to "self-restrain if they want anything vaguely resembling a balanced experience" is AWFUL game design, not to mention and an idiotic, incompetent approach in general.
Especially when you realize that in its essence a game is a series of interconnecting, interacting sub-systems that is defined by its limitations just as much as its possibilities.
Chess wouldn't be chess is players would be allowed to change a piece moveset at will when he's in a tight spot.
