How do you brute force your way through a boss?
Everyone seems to have mixed opinions about the difficulty. Some say it's too easy, some it's too hard. I thought it was just fine. I know that I leveled past some of the quests, but chose to do them anyways because I thought they were fun. I find the difficulty to be just about right. I don't hold Gearbox accountable if I choose to ignore a quest to do other things and then go back later and do them overpowered.
This is one of those, you can't please everyone kinda games. Being underleveled definitely makes for a challenge. I tried to fight *mid game spoiler boss*
underleveled and got my ass handed to me. I had to respect differently and managed to do it without grinding out a few levels.
