I think the damage the assault's grenade launcher does to the money ball needs to be nerfed. An assault with RoF 3 Crit 2 Clip 1 (My build) Can do more than enough damage to virtually take it out in one clip. Plus, you can bounce it off walls and etc. so you can easily be outta harms way.
maybe it could at least use a 1/4th damage drop when juiced (and at very least to the moneyball), but i could think of other things that make the assault a lot worse. generally, the entire richocets into the moneyball thing could stand to be fixed. fixing it is a problem tho, you cant just make it not damage the moneyball after it bounces, the game doesnt keep track of when a projectile richocets. idk how they are going to fix it, make some kind of special shield around the moneyball that blocks grenades and shurikens in general (yes that would nerf the assault, i play assault and i say thats better than ruining a perfectly good game)
I've always been amazed how easily Assault can chew up the money ball. It might be an intentional balance to the fact that they are the absolute worst class at dropping turrets, making it damn near impossible to push a lane and drop the ball without help. They are called Assault, so the name does seem appropriate.
