The secret to jibbers is dedication. I waited until I was at a point where I was ready to take a break from the game (and thus didn't have any real desire to play). Instead of just not logging in, I logged in and ran TTT once on epic hard (this was back when epic elite was too tough for most people to solo). Whether it took a month, 6 months, or 17 years (to use your example) I was determined to run it just once a day and do nothing else until I got it. If I ended up farming a dozen epic past lives just running this one quest, so be it. Took a couple of months to get the blade. It's drop chances are not that low if you are getting 365 pulls a year.
