As you can see here, CCP plans to release a knife for each race.

That being the case, why not have each Scout suit get a bonus to its faction's knife?

2 bonuses only "forces" a role onto a suit if the bonuses are constrictive. There are plenty of non-restrictive bonuses that don't pigeon-hole people.

Also, before you try making a suit that uses racial knives, you have to think about the knives themselves. What would be the difference between them to make them non-redundant?

The only thing I can think of for another knife is one that straddles the line between the uncharged and charged damages of the nova knives. You won't have to charge it and will do more than an uncharged nova knife, but will never get the damage of the charged knife. That's a trade-off bonus and would make the knife different.

But that's only 1, and two more would have to be thought of. What else is there for a knife, really?

And @ Krom, I appreciate the effort you put into your post, but I won't ever support giving our futuristic soldiers swords and maces(Khumaak in your post). Knives (or knife-like things like ME's Omnitool) will always have a place because of the utility of it. I don't want this to turn into Medieval:Future Warfare.

No doubt, but those are for ceremonial use, not actual use on the battlefield. I'm sure that they'd be able to make due if the need arose, but deploying troops with such would just end up looking like this.

Too bad.
