I'm glad I cleared on the attempt where 5:50 happened, it's a perfect representation of getting to damage in this fight. The final shape changes didn't really affect the overall difficulty of the solo too much, but the envious assassin "fix" that happened recently makes this fight so much more annoying. You can now only get ~14 in the GL mag as opposed to the ~21 you previously could, and you need to make sure to get a weapon kill just before getting to the DPS spot to ensure that you don't have only 7 shots in the mag when you equip the GL during DPS. Still not the hardest challenge in the game, and still a decent way to get some RoN loot solo!
