Exactly what the title says. People who don't manually set their defense shouldn't have their defenses set for them from the top of their rosters. It makes the attacker's job exponentially more annoying and essentially prevents him/her from working towards any of the feats. The auto set defenses should be pulled from the bottom of people's rosters. If you're too lazy to set your defenses, you don't deserve to have a tough set up and certainly don't deserve a shot at winning.
I'm still cool with it autosetting the last known defensive set up, like in the previous round. But these hodgepodges of R7 toons sucks the fun out of the game mode.
