I can provide a small example of this frustration. Again, anecdotal, based on our experience. It is NOT a condemnation of steam or valve, merely a mild example of these frustrations from a developer standpoint:
So a few months ago this review popped up:
We'd made no changes to the game for months, certainly no changes to the throwing system. This person also posted in the support forum, where we were troubleshooting this issue with a couple other people who had experienced it (it was random and rare). I enlisted one of the main programmers to take time out of his day to try and troubleshoot the issue with me.
Within a couple days, we found a solution - turns out a recent steam VR update had nerfed throwing for a couple of players. THIS person was part of the discussion, and acknowledged the fix worked for them.
We responded to their posts in the forum, and responded to the review as well. I've actually asked this person to reassess their review as the game works for them.
Here is where the frustration stems:
-the user has no interest in changing or removing the review (it's the only review in his account). This is despite us taking the time to personally address his concern.
-we have no way of removing the review or flagging it as a resolved support issue.
Now, For the most part we have been lucky - the vast majority of our reviews have been positive, helpful, and kind, and the one or two negative reviews we've received were on point and actually helped us tweak certain elements for a better experience. I can say without hesitation that the fan support on steam has been wonderful, small though the base may be.
But being unable to filter chaff like this is frustrating. There are certainly worse examples of this as well:
It was early enough in the games release that we actually tracked down his argument via a google search, which was with someone else not affiliated with any of us. We tried explaining it to him, but he'd already fucked off and was long gone. Flagged it, finally got a response from a mod which basically said "deal with it and move on".
So there are definitely areas, I think, where this system could be improved or served by dedicated support.
