I can see that point for sure, we launched with bugs that had impact on the overall experience for sure. The thing is, we try to fix everything we can reproduce and there's no reason for us to try to slither around these things.
We require player input because players are experiencing these things and millions of players playing will just ultimately always have more hours played than our QC teams, just by sheer numbers.
That doesn't mean we're not testing these things or are not experiencing any bugs. We do and we fix them. But some things we can't reproduce and that's where player input is just super valuable and can help us fix things.
A simple example is one of the sound issues that arose early after launch. Only after players told us they were using specific headsets with a specific software we could identify the issue, buy the headsets, install the software and fix the bug.
