If they had been more transparent with their ideas that went into the game and actually listened to and gave feedback to players, there would have been a lot less backlash.
Just look at how most PTRs were done. One (lately two) week to test surprising major changes, one week of absolute silence and then the final patch notes. It’s ridiculous.
Also, for years now people have asking for a major balance patch (ex. Patch 2.7 re-balancing mega wish-list) that would require mostly number tweaks and not new mechanics, it never happened.
