Width Tool Changes When Adding New Points or Mirroring and Joining Objects
This issue really affects me, especially when I create an entire path, but then gets destroyed due to more points. Could you consider getting rid of width profiles or make an option to disable it? I want the width point to stay at the exact same place all the time just like anchor points! Also the width tool points can be very inaccurate, as shown in the picture below.

But when I add or join points is when it sucks.
Illustrator tries to maintain the positions of width profile markers when they are snapped to points of a path.
It is definitely true for closed paths, like the one you display in the screenshot (please correct me if you have cases to prove it).
For open paths it’s trickier — the profile gets stretched, to fill the entire length of the path, and markers shift from their positions, whether they were snapped to points or not. There is a separate request on this you can upvote: http://illustrator.uservoice.com/forums/601447/suggestions/38084425
The same problem happens when you try to join or cut paths with profiles, and there is another report: http://illustrator.uservoice.com/forums/333657/suggestions/44457144
Is this what you mean?
But then you say 'getting rid of width profile' or 'disable it'... This is where I trip. Well, you obviously can disable them, that it to remove from a stroke: with a Profile dropdown in the Stroke panel, assigning the top 'Uniform' profile, or in Control panel, or through Properties (which is just a longer way to full Stroke panel)... so I assume you mean something else.
I suppose at your screenshot you refer to the bad joint on the right? Yeah, Ai does not do sharp corners well when it’s a starting point of a path (even closed paths have to start somewhere). A workaround for this for now is to cut a path at some other, smooth point (although this particular path seems to have only two sharp ones) and rebuild the profile. Another way is stick to art brushes — which are much harder to control though.
So it’s a valid report about this joint, and I am converting it into a bug report instead.
If you are able — please add the demo for the way it fails on mirroring though. Do you mean a Mirror Repeat, or the Mirror tool?
If the Repeat — again, there is a separate report: http://illustrator.uservoice.com/forums/601447/suggestions/45205540
