I completely understand this suggestion if you're someone who has no patience and cares about squeezing in an extra 2 minutes of runs but honestly, you should try getting used to just taking a breather. Have a little emote session, a drink of water, a snack before the next round... This timer is healthy for an activity that can be very long. As someone who has been farming 10 waves then resetting, this timer is the only thing that gives me the chance to quickly go to the toilet and come back. If I went afk mid round on legend, it would be GGs.
