I find some of these shorter connections QR is selling (anything under 90 minutes, really) increasingly risky. During arrival bank times, there can be arrival delays and then you really do not know where you end up. From certain destinations, you are almost guaranteed a remote stand followed by a scenic bus tour. On a short connection every minute can count, and the terminal is really getting massive. Although QR will rebook you in case of a missed connection, that is not really much of a consolation if you have to actually be somewhere on time.
