Memento-PFE-Drone Build / Solo Attempt Legendary DISTRICT UNION ARENA /

The quest to create the safest, laziest Legendary build continues! And I forgot to hit the record button until partway through. But, as we can see, the build seems safer than the Stand Your Ground build because we can stand toe-to-toe against Legendary enemies. In turn, this allows us to shoot ouf of cover for MUCH longer. However, without Sawyer's Kneepads explosions are a danger again and grenadiers need to be focused more.

Original build video is here at the end of the runtime:    • Navy Plaza using Memento-PFE-Drone Bu...   and there is one important change. I switched the Banshee's talent to Future Perfect. As this weapon kills enemies, the drone grows more powerful reducing damage 40% up to 60%.

I'm thinking I can next go Firewall, Gunner, or Technician with this build since I would only be losing 10% PFE... each has their benefits.

Gunner = Less strain on ammo, 10% Armor on Kill, Handling, and ROF boost.
Firewall = Better med kits, Massive short range damage boost using Striker Shield.
Technician = Future Perfect on SMG can theoretically reach Overcharge.

This build isn't designed to be quick. It is designed to be EASY and SAFE. The goal is to create a single build that doesn't need switching throughout the mission.
