So, let’s say you won the first four flags of the day and the fifth match gets you facing a defense team you stand no chance to defeat under normal circumstances… of course, you can’t re-roll, but what happens if you decide not to take the fight. I guess you will loose that flag and start the next day with 5 flags. But what happens to the enemy team? Does the new day reset your match or will you still face the same unbeatable defense the next day?
This is only a hypothetical question, of course, wasting the flag gains you no points at all, while loosing the battle still gets you the points for the enemy heroes you manage to kill.
