Some ideas to balance the game
I just have feedback to make the game maybe a bit more balanced. I say for smaller characters(Wraith and Lifeline) we should give them the opposite attention you gave Caustic and Gibraltar. Wraith has such a small hitbox and she has the ability to vanish, so my suggestion would be to give them a bit less health then other characters. This could make up the balance between some characters that are bigger and smaller. Lifeline has ability to heal and wraith can dissapear. Just an idea that you can choose to suggest it or not.
Another suggestion I have is how to balance the wingman. Maybe just make the wingman a 6 round mag with no ability to extend the mag. Since the gun already does heavy damage equivalent to the longbow. Also just add reload time to it and make an actual revolver reload. I don't believe the wingman should do just as much damage as the longbow, but if it does it should be a smaller mag of 6 only without being able to extend the mag and adding reload time or decreasing damage.
Again just a small suggestion that may work or not. Just wanted to give my two cents. Thanks
