So some guys I was playing with were power leveling my Axton alt in TVHM as they were completing the story quests. Now that I'm in TVHM I've gotten to skip a mission or two because I completed them in co-op.
Well, this last time I got the opportunity to skip ahead was just after the Sanctuary flying away mission. I ended up skipping all the way to the mission where you attack the bunker and Angel (skipped the quest to meet Brick, the quest with Bloodwing, the quest in Opportunity, etc). I'm currently level 36 and the enemies are level 46.
