I've seen this with a few turn based games but I will say this again. If you have an auto battle option/button built into your game then you know you've made an unnecessary grind of a battle system or high encounter system and need to start over. Which leads to player fatigue when it comes to turn based combat and an avoidance to turn based games. Grind Grind Grind love it or hate it the devs heard this major complaint from game journalists all through the 90's and early 2000's.
