If im not mistaken, Feat's are Kill streaks. https://www.youtube.com/watch?v=sp3NKQlJPuo Starting at 3:29 you'll notice Geoff Ellenor #TeamSamurai Unlock his Feat. 4:16 You'll notice Geoff Ellenor call down an arrow storm feat. <.< Put 2&2 together and you'll assume Feat's are Kill Streaks. Also #Forhonor has been Describing its self as "The Shooter with Swords." Really wouldn't surprise me if they borrowed some element feature's from CoD.

The killstreaks should be similar to Medal of Honor/Battlefield, where you can choose to have a defensive/supportive killstreak bonus, or an offensive bonus.
Also, I don't know how the scoring and teamplay works in this game, but if there are other ways to get score rather than just fighting, then instead of a kill streak, a point streak may be more viable, so people actually do objectives and such.
