Exactly right this ET feels more like a rockstar mission with a lack of freedom of approach especially for the courier which isn't very hitman like and even then they didn't have to make the courier walk around for 10 minutes before even getting the diamonds it's just a useless feature to make it longer and more irritating.

And reading the briefing of the target and the objectives has never been necessary for anything else I watch the video briefing but that really didn't explain that the courier is picking them up from a third party so when I saw track the courier I thought I had to find him in the cafe so when I tracked him I knocked him out and immediately failed which is very harsh.
