Not sure if this has been brought up yet, but with the introduction of Paradigm Shifts in FFXIII, combat became "one-button" combat. Sure, you picked what paradigm you wanted to be in, but unless you were a madman, you always selected Auto-battle from there. This just sounds like the further simplification of that. Not saying it's what I want, as I thought the removal of player choice regarding individual attacks took a lot away from FFXIII's combat system (which otherwise was probably one of their best modern combat systems), but it's not like this idea of simplified combat is something wholly unique to FFXV in the Final Fantasy franchise.
In fact, given Nomura's influence on this game while he was at the head of it, it sounds more like another step toward Final Fantasy playing like Kingdom Hearts.
