Lots of times I’ll find a bug, go to report it, and find someone else already reported it. Then when I find a workaround, I post it on their Answerhub thread so that everyone can benefit. The same thing happens on my bug reports. I feel like this change is going to kill off a lot of discoverability, communication, searchability and community problem solving.
And it is going to make following up on your own bug reports difficult if you find out more information. There will be nowhere to post the additional information until things have gone through several steps.
I don’t really mind if it is through Answerhub or not in the end, but it would be nice to be able to comment on the bug reports and easily keep track of them. Otherwise this is almost just like the crash reporter.
