The only real problem with them is that the game doesn't tell you that you'll need to do them until you hit the point where they're required. If I had known that ahead of time back when I was working through the ARR MSQ, I would have spread those three out during downtimes in the story. Instead I had to do all three in a row, and it was annoying. Just find some way to encourage players to do them beforehand and it'd be fine.
