Titan

Punishing and high damage output with creating quick stagger. The combination of both the bazooka and dual diffuser cannons will take a significant amount of damage up close where it will end bosses and melt ACs. The laser rifle can be changed, however the fire rate makes it more desireable as well as damage output for low tier enemies. Using the bazooka and follow up with the diffuser cannons is possibly the best counter for melee enemies and even for enemies that like to keep distance. Close the gap and use the diffuser cannons, bazooka, then diffusers again. You can fire the diffusers together about 5 times before needing cool down. Charge them to do more damage to pulse shields or shields on bosses. This build can go through an entire playthrough with no changes needed.
