This is incorrect. I'm a 100% auto-fighter and would massively benefit from this change. Instead of losing 100+200+100+200 you'd just lose 600. Exactly the same outcome, just fewer clicks.Having fewer encounters but larger troops sizes would benefit those who manually fight but not be good for those who Auto Fight.
Please stop spreading baseless fear. It would most likely be random(like it already is) and therefore the same losses on average as it is now.If you have 4 encounters and lose 100 units in the first, 200 in the second 100 in the 3rd and 400 in the 4th, which encounter do you think inno will choose to make it less tedious? The easier ones? Highly doubtful. Most likely the 4th one, now quadruple your losses.
I'll even add that as part of the suggestion so you can stop bringing it up.
