Quick battle.

The main purpose of the autobattle, even since the third installment, is to save time when playing against other people. Good players always play against neutrals using the autobattle, only taking over manually when there are critical losses. This shows basic respect for the other player's time.

Here, you are wrong. I haven't played the sixth game online yet, but in the fifth, good players set a minimum of 5 minutes and try not to incur any losses at all. And respect is no longer the issue – if you don't have the time, don't play, although in the fifth game, there were simultaneous turns, but here, that's not working. But for me, even here, the priority will be the integrity of my army, not the opponent's time (of course, if the autobattle will be without losses, then I will agree with it).

Above, in my post, I wrote about playing in the campaign.
