Game can get boring after a couple of playthroughs but today I finished the second playthrough on my siren character and I like how after you do that all the vending machines sell level 48 gear and all enemies are 50+ or close to it.
My build and classmods are all boosts to my phasewalk and so when my phasewalk ends if i kill someone right after it'll be ready to use again. My phasewalk is level 5 corrosive, i have level 9 radiance and i have a 4x fire smg so i just stack all 3 elements on all the enemies and they drop really fast and it looks cool
