I still make reports regularly as I play all the new betas. Feels like more or less the same rate as always, game wise, but I don't keep track.
It IS more involved to check for duplicates since they revamped the bug system, and have ignored requests to simply place a button to see all reports for a game. They comically added a button AFTER you submit the report.
And there is also another classification layer when creating, but I don't know if that would discourage things enough. Maybe yes, maybe no.
For me, sometimes I ignore checking for duplicates now, although most of the time I do verify that there isn't one already there.
