MMA isn't just a way of saying you use strikes and groundwork, it's what it says it is > mixed< martial arts, the use of many techniques from many styles in a competitive fight environment. It's physical chess, outwitting your opponent and winning the fight, it's knowing what to use when, it's using your opponents weaknesses against him, using your strengths and generally enjoying yourself in a fight! I've no idea what you mean by 'the day of that seems far less simple than it used to be'.
