Heroes Should Be Rebalanced For Galactic Assault and Supremacy

Heroes are too powerful for as easy it is to get them and then steamroll matches. 

I would like to see them either on a timer so you can't just hold them the whole match or their needs to be some kind of massive nerf and meaningful counterplay instead of just getting bum rushed and murdered by a better hero wins team.

When the enemy team has a maxed out enemy hero the game is unplayable.
