City of Heroes/Scrappers

At release, the animations for Katana were identical to Broadsword. With Issue 2, the animations were completely redone, and much improved. Katana uses less endurance than Broadsword, but doesn't hit quite as hard. It is faster, though, so the damage per second is good. It's a well rounded and effective primary. Like the broadsword, every time you hit an opponent with your katana, it will reduce their defense, making it easier to hit them again.
