Many of us have widely different artifacts in the main room and in the War room of the museum. For instance, while I have a rather large loot bonification in the main room and more modest defensive bonuses, I have upped my war artifacts as much as I could thus far. Neither my my defensive buildings nor my troops have the same stats in multiplayer and in wartime, but the home screen only displays multiplayer stats. Unless I patiently run the numbers, which is bothersome, I can't know the damage inflicted by my units and defenses during war. It would be useful, I think, to know how the stats are affected by artifacts in each case, instead of having only the multiplayer stats displayed.
