How to effectively use quick battles (autobattles)?

AlexSpl, thank you for the information. We will have to post a ban on the use of quick combat at the WCL tournament today. Just in case someone uses it. Unfortunately, we will have to check games more often, which takes up a lot of time. Or, as an alternative, we could restrict a) the use of units that don't retaliate and b) additionally ban the use of quick combat if the total health of a player's army is clearly less than the health of the neutral units.
