My little brother wants to download this game, So he asked me to do it for him. He is under the age of 16. Is this restriction overly protective and its fine to play, or should I tell him that he is too young?

The Brimstone, Viper, and Raze on the friendly team continually sabotaged the team by cornering either me or the Reyna and proceeded to kill us using acid, grenades, or Mollys. The enemy team was just fine. PLEASE DON'T HARASS THESE PLAY...
