I had the same experience and was also curious how the rest of the game holds up. I had big issues with 15 due to repeatable side quests (I like to clear all sides quests before moving on to the next area) so I was super overleveled the entire game.

that may exacerbate things.

depends how big the project is. large projects benefit from it being broken down into multiple smaller projects and communicated from week to week to coordinate. but smaller projects, it’s just a giant waste of time.
