It makes the wave sections a cakewalk and wave sections are the other half of this game. In fact, I'm certain FB shaves more time off for players than BH does. BH only useful against stationary bosses, FB useful anywhere from missions, patrols, non-boss strike sections, raid sections without bosses. Killing adds is a crucial component in every activity in the game and FB is quite easily the best primary in the game all-round allowing you to strut Gally as your exotic of choice. Plus it has arc burn and it is the most common modifier in the game thus increasing its usage even more. According to Bungie logic it should be nerfed. A team with only FB can breeze by every single wave section faster than teams without it!
