okay, so I'm currently playing Marvel: Avengers Alliance. and every superheroes I'm using has their own classes. now, to help me remember, I'm gonna put the explanation on this post according to Avengers Alliance Wikia. there are 6 classes and here's the list:
Generalist
A Generalist is a Hero or Villain with no real class, thus having no strengths or weaknesses. The player's Agent starts out as a Generalist before they buy a class Uniform, and many early bosses, including Viper, are generalists.
