Number of troops killed in a battle

At the end of a battle, it always shows what troops you used, how many, how much loot you got, how many trophies you won, etc... I think there should also be a red number next to the pictures of the troops used, that shows how many were actually killed by enemy defenses, bombs, and clan castle contents. This could also be shown on your defensive battles as well. That way you know how exactly how well your base is working without watching the replay. Even with the replay, its hard to tell exactly how many troops you managed to take out.

I think it's best to asses how well your base is working depending on how many storages are taken not how many troops are killed. 90% of the attackers troops may get killed but still have 3-4 storages taken which would be more reliable in analyzing how well your base is working.

I don't think it's necessary to show how many troops got killed, we already have sufficient information after the replay.

I guess you're right, but i would like to see how many troops die in my offensive battles

Understandable, personally I don't think it's necessary to see how many troops died while I was attacking as long as it's successful. Battles tend to use random amount of troops at times depending if you're going for collector or storage raids. I have a feeling you may be in the minority of players who want to see how many of their troops got killed during battle, but I may be wrong.
