I get what you're saying. If the time system was the main thing we wanted people to pay attention to then we would not have changed it.
The way I see it, the game is first and foremost a push-your-luck game. I love those juicy decisions about whether I want to be greedy or not. To me, the time system wasn't important for that, so I'm OK making that part a little less deep in exchange for it being easier to understand *so that* we can add more complexity elsewhere in the game later on.
