The free edition doesn't have families, though. But with something as big as a MOBA, I would start to look into some serious data structures. Just looking at what you need, here's an idea:
-Make all your characters one object with a bunch of different animations.
-Make an array with the names of all the different animations (e.g., P1Walk, P1Idle, P2Walk...). Put different character types along the X axis and different actions (walk, idle, etc) along the Y.
-Give the character a number variable for which character it is and another for what it's doing.
-When you want a character to do an action, have the events change the value of the action variable.
-Finally, add an event like this one:
Every Tick - Characters play animation array.at(Characters.identity, Characters.action) from current frame
