As a former player I hate mercy rules due to a clock being used for soccer. Eventually time will run out. You can use a continuous clock and even 'shave' some time if you wish. However, the biggest issue to me is scheduling. Why schedule a team that you're going to beat 10-0? I know region opponents have to play each other, but non-region should never be a huge discrepancy. The other argument I have though, is it's hard to play 'other players' on your team if you're in a 10-0 game and you give up a goal and your region tie-breaker is goals allowed or differential or something like that. You end up screwing yourself.
