In my opinion, don't take it and don't give it!

The negative consequences have been verified through personal experience.
1. When you know what they'll give you in auto-combat, you'll lose concentration, and this will become a habit over time – then it will be very difficult to readjust in tournaments or other games with different rules.
2. You'll never learn to calculate the outcome of a battle before it begins, the number of monsters, the size of the stack (!), the probability of morale, etc. This is a step towards a higher level of gameplay.
3. When you give auto-combat, you psychologically relax again and expect a response – this shouldn't happen. If the game is more for fun, then it's a different story.
4. If I take auto-combat, then I can't consider the victory to be complete :smile50:

P.S.: I still give auto-combat, and I try not to take it, even when offered – it's very difficult at first, but then it becomes beneficial.
