Also preposter is right about Legendary swapping. Shoulders+Bracers are only good at a low number of Mobs/Single target. With Fortified best combination of AoE Legendaries for trash might be Gloves+Ring afaik this combination will grant you the highest amount of Sustained AoE the game has to offer, however for burst while having Tyranical and trash mobs dying kinda fast Shoulders+Gloves are pretty much ideal. If you dont have the Gloves, the Ring is really good to sustain your AoE. The Trinket is useless due to its long CD. If you dont have two of these Legendaries: Ring/Gloves/Shoulders, its not worth to swapout your Bracers for trashmobs, you probably wont do any better without two of them.
