I'm going to have to go with beating the original Titan as well. I forgot the name of the guild I was hanging out with during the time (sorry guys, it's been a hot minute!) but after an entire weekend of trying to finish him off, we finally succeeded. I was also able to obtain the main quest weapon.
I was so close to grabbing a handgun and shooting my laptop. #RageQuit
