And almost all of the weapons for blowing them out of cover were either nerfed or removed.
You could probably take super and fireball at this rate. Pop them with the fireball and hide, forcing them to have to come to you.
If anyone tries to use anything to break you out of cover, just shoot them with the shotgun. You'll outdamage anything they can do that with.
The only thing that could possibly win in this situation is spiral missile, or a really good player.
