I tried reaching relatively high levels before facing most of these bosses so it wouldn't take too long to defeat them. Since the boss battles were actually set up a lot better than Borderlands 1, they all took a lot longer to defeat so sorry for the video length! I skipped ALL none cutscene bosses. All done in Playthrough 1 (obviously) Asus G73JH Laptop on Max Settings (Except Nvidia Physx)
