If a newbie only plays battles using autobattle, then their micro-management skills won't improve, that's true. BUT! The newbie needs to understand that if they don't move beyond autobattle and learn to micro-manage, they'll remain a newbie. There are people who understand this, and they will improve, while those who don't understand these basic things will get zero results, whether autobattle is available or not.
P.S. I'm not very good at writing long texts, but I hope the point is clear.
