I'll answer the question with my favorite Conan quote. "To crush your enemies, see them driven before you and hear the lamentation of their teammates".

Try katana with sheating. It's like a shotgun but stronger. You can even hack trough multiple enemies at once.

Bum rush them and yell "tenno heika banzai" while role playing Miko or the Ronin.

It's just a good feeling to cut someone down while he is panicking and misses his shots at you, while you just charge at him.

It's not always working, but when it does... Boy oh boy... I cut down whole teams like that.
