Not sure if anyone noticed it, but they are going to be releasing the highly requested "Auto Battle Mode."
Taken from Taringa:
"NEW AUTO-BATTLE MODE"
"Now you can activate the auto-battle mode in Dungeons!"
"Try the new auto-battle mode in the Dungeons! It will allow you to easily sit back and watch your monsters fight. Don't have much time? No worries, because with the auto-battle mode, you can
choose the speed of the battle."
It will be interesting to see how the AI behaves, which may give a better idea on how to build your defense.
Kind of nice to fight through the easy dungeons as well.
