I think it would be really nice to have some stats (showing total hits/damage taken or given for example) at the end of battles. It may not be very usefull to the game , but would add an nice little "battle end" and may improve player satisfaction after a battle and , most importandly, may help analysing post-battle what worked out well and what failed. So we can improve tactics and designs.
