Given that it is possible to engage in multiple battles on the same turn and that it is possible to exit the battle screen to change view, I think it would be nice to have a way to keep track of what has happened in the current battle. More so in Multiplayer, where rather than wait for your opponent to think his turn you might want to manage another battle or your empire.

While replaying the entire battle is possible, albeit cumbersome, a more friendly way to handle this could be to only show the last turn. If replaying the entire turn is slow, in my opinion a faster way to display it would be to do the reverse of what Endless Legend used for its battles: show through arrows what happened in the past, not what might happen in the future. Red lines can show attacks while White lines can display movement.

I think for Multiplayer this would be nice to have due to the waiting you'll do for the other player to execute their turn. Waiting for them to decide, even with a timer, will get tiresome and I think this offers an option to do something else in the meantime without losing that information.
