Seriously, I hate this quest. It is by far the most difficult thing I have ever attempted, and this is coming from a guy who's second "Mass Effect 3" play through was cranked up to Insanity. The best part? I don't even think The Chaperone is worth the trouble.

The simplest answer is to get it for the sake of completion. If you like the gun, fine. If you don't like it, don't use it... sooner or later Bungie will probably adjust it at some point, but at least you can say you have it.
