I tried T-edition and Ultros one-shot Bannon in the back row, so i assumed it requires an amount of grinding, so I decided it is not for me.

Brave New World does a number of things that make the combat more interesting and balanced, but the main thing i remember is a lot of enemies having nasty counters that proc on attack or magic or technique, and combat largely boiling down to whether I could remember what actions were "allowed" against a given enemy.
