Guild Wars 2

The Charrzooka only fires one shot. Before the update it fired many.

New content update later, Charrzooka still shoots one ammo.

I assume you’re talking about the consumable item. This was an intentional change that they made with the changes to summoned pets.

E.g you can now summon only one pet from a consumable. Charrzookas etc now only shoot once

How do you know if this was intentional?
