Even a single application of Bravery or Faith on your leader on the first turn before shifting to Cerberus will prove to be much more efficient than Cerberusing the entire fight. It's simple math, really. Not when most fights last less than 20 seconds only using com/com/com and can be 5stared without anything but tapping A. Hell, usually I do not even have to look at the screen. The game is very unbalanced with the majority of the fights super easy and only like a quarter harder. ...but about 10% are a real challenge and provide some major difficulty spikes.
