It's quite complicated, and at a very broad level I'm vaguely reminded of Final Fantasy 13, a game that could look like hitting X on auto battle over and over again but that actually was all about shifting between carefully pre-determined battle load - outs that could actually get quite stressful in its challenge.

Strategy can be disregarded and all three party members can be set to auto battle if any time is spent leveling up Estra and her crew. (wccftech.com)
At first it seems like the combat's been oversimplified when you select Auto Battle and all the moves are chosen for you, but it's more an attempt to move to higher - level strategy that becomes very successful as the classes and abilities begin to open up. (pcgamer.com)
