Please fix the MMR system finally

Those 'tanking' teams were bad enough dumped into lightning to get boos on some other event.

Now it seem to go inside tournament, combining bagman teams with shields to gain smaller opponents at no point loss. Not sure if it actually works, if it does please prevent this exploit ASAP. If not just please announce to stop people doing this as I believe even attempts mess up tournaments.

And in general gaining benefits from losses should be prevented entirely, it goes against everything involving competition.
