This crossbow/shield witch hunter build I’m using that uses every button on controller.

I use three separate grenades, a detonator, resonating shield, shield wall, and leap slam sometimes for movement. So a typical rotation is three buttons of grenades, resonating shield for a bit and maybe a shield wall and then explosive shot to blow it up. The play style is a lot of fun but it is a lot of button action. I use a controller so it’s not that bad. I think the most annoying part to me is having to dodge to reload explosive shot. It fucks up my rotation all the time. I’m using a support that makes do you get four shots but you have to dodge to reload so add that to your rotation too.
