For a siren it is really easy with the right build and knowing the fight some. I can get him down (i have an smg with ammo regen, but i prefer just using an ammo regen mod and a more powerful smg) in right around ~3-5min. I typically don't kill any of the adds unless I need a second wind.
In a siren duo, 2-3min is about average if both know the fight.
Takes longer to pick up all the guns lol.
It takes a couple of deaths if ur trying to solo for the first time, but it gets really easy. If you need some help or tips lemme know.
