That is generally referring to feedback on support related topics. While all aspects of game development impact the support to one degree or another, as it does impact the player, that doesn’t specifically make it a support issue.
For feedback on the event and how these things are rewarded, it is best to submit feedback in an area that our Community Management and Game Developers can see it.
Providing advice on where best to post your feedback, or suggesting that you do it at all, isn’t providing advice about the Code of Conduct. It is doing exactly what this forum was designed for, to provide advice and guidance on proper methods of contact or what to do if they have an issue.
