You do realise that Boubou is a fellow player, trying to help you, right?
You’re claiming something doesn’t work, but other players are showing it working for them, and explaining how it works to you. This means you need to provide evidence of it actually not working and, preferably, with screenshots / video showing it not working and detailing the circumstances under which it can be replicated, so we could test it too and confirm if it also doesn’t work for us. There’s plenty of people that are willing to test something if you have a scenario under which it apparently does not work.
The How to Write a Good Bug Report at the top of the forum says…
After your Summary, include a brief description of the bug you experienced. Include as much RELEVANT information as you can. Where you in multiplayer? Could you reproduce the issue? Specifics are preferred as we need to know as much as possible about the issue.
If you have steps and can reproduce them consistently, write them out. This will help Quality Assurance get a must faster turn around time reproducing the issue and reporting it to the Diablo III developers.
Finally, it always helps to attach a link to Imgur (or another picture hosting site) that displays a screenshot of the bug. If you need to include a video, link to a video as well.
