I think it would help to see a few more stats in the battle stats box right below clan gold. First would be "Average Damage Done Per Hit", second would be "Average Damage Taken Per Battle" and third would be "Average Hits Per Battle"
There's room for them and this would help see better when you were strong enough to move up mobs as well as giving other general good tracking info for your progress. Plus there's already all of them tracked in single battles, this would just add in those averages. You could also add in dodges per battle too if there's room.
