Play smart & know the class you'll be fine. Just play smart and listen for the sound of the hammer being activated and be ready. You shut him down with focused fire/strong shots and hey if you have to use your super to counter him then go ahead because honestly it isn''t a waste since you could save your team/yourself. Meet a super with another super. Snipe him out and use cover to block the hammers The throw speed isn't gun level of fast so you can dodge and have time to move. People just need to get used to everything.
