Just a (potentially dumb) thought regarding game balancing:

What if we were to only equip and use 2 gadgets instead of 3? Where one would be customizable and the other set to that specific class. I know weapon sling works in a similar way, but I'm thinking on a more broader scale. I believe the battlefield would be more readable, less chaotic, and perhaps more balanced. I believe the classes would be more acutely defined as well. Also tank controls need improvements, etc.
