Well, your rulebook says you can quit the connection twice before the two minute mark and after that you have to play disregarding the lag. We played two full games with lag before and decided not to play the win-or-go-home game with that bad connection. Yeah, we could have started it twice for 2min and than we had to play it anyway. In a more and more competitive league, connection issues should be solved in a better way instead of: "Try it, change host, try it again, change host and then play it. Just bad luck buddies."
For us, the fairest decision would have been to switch the games to the next or any other day and play them regardless of the connection. This would give both teams a chance of a better one on a different day. Should be implemented in the rulebook that there is a free day between the rounds for technical problems. We all know how the servers are from time to time and loosing because of that is more than devastating.
