One thing about launch angle is that is measure a pitcher better than a hitter. It describes what kind of pitcher is on the hill. A ground ball pitcher or a fly ball guy. Launch angle is expected to answer that question. It is accepted that ground ball pitchers tend to be more successful  because they avoid allowing the home run and many types of extra base hits.

It does have some importance for hitters, too. A hitter with a high launch angle is a fly ball hitter and is likely to smack more home runs and/or extra base hits. On average, fly-ball hitters generally drive in more runs than ground-ball hitters.
