Give fireteam a Samurai sword. It’s not like it would be out of context either.
Heck, make it a two handed weapon in our hands. Slower to attack and harder for us to parry pred, but also do significant damage.
We all have seen the movies, books, comics, etc. Can’t tell me it wouldn’t fit considering it’s been a thing for humans. But instead you gave it to a pred only? Don’t mistake me though, I love it on the pred, but it would also be quite useful for the fireteam as well. With or even without a class designed for it.
