"now to the other facts: to exploit something you need a personal gain, therefore there is no personal gain or loss to anyone out of the banish if you refresh. the only loss you would suffer is if you do not refresh, then you would suffer the (originally unexpected) extended rounds in gameplay that go past the 1 minute deathpenalty while the game continues."

In other words -- there is a HUGE personal benefit to refreshing. It means you do e.g. 75 million damage each minute, rather than the same 75m damage each 5 minutes. So you do 5 times the damage. (more or less). And get 5x the rewards you would have gotten if you didnt refresh.
