But you're now qualifying it as "constructive", which is raising the bar. If we simply say "feedback" or "criticism", it isn't mental gynmastics to say it doesn't have to be constructive.
There generally isn't an expectation when a customer complains for them to provide an answer as to how to resolve the issue or even a detailed understanding of what they dislike about it. The business can ask what would improve matters, it might even probe further to identify what if anything went wrong, but it's absolutely not a requirement for something to be constructive for it to count as feedback, and even SE's own mechanisms of gauging customer dissatisfaction e.g. on unsubbing, are pretty minimalist. If they are content with that level of feedback when a customer terminates a service with them, it's a bit bizarre to expect more of a forum, which is not really seen as anything other than a venue to discuss the game with no particular expectation that feedback provided will be constructive... even if as an ideal it is. Thus my point that if their employees are going about reading social media feedback, while he can certainly request that consumers be considerate, but he cannot ultimately control what customers say and so the way to address this is to coach them on it or have staff who specialise in this sort of work to do it. It's only natural for people to become attached to their work creations, and it's good to see he is supportive of his staff, but generally speaking it is advised to either go in with a steeled mindset when reading feedback or to have someone who is detached from creating the work to do so to avoid situations such as this. And I think for the avoidance of any ambiguity, he should provide examples of the general behaviours he mentioned.Saying that the healer design is shambolic because the damage rotation consists of nothing but DoT > 1, 1,1.. 1, > reapply. That is constructive feedback. To take it a step further, if you introduce examples of how you would make the set more engaging, be it through reworking the encounters in the game so there is a heavier demand on actually healing, or through the introduction of some new damage spells, then that's great. However, if your only statement in this regard is that the developers don't play their own game, and that they should be fired because their design philosophy does not align with your own. Then as per my initial statement, no amount of gymnastics will make that feedback any good.
And all that goes back to what is the purpose of a forum? You may think it is to elicit constructive feedback. They may simply see it as a way to increase customer engagement that occasionally produces some feedback that is of use to them. Same with third party social media. At the risk of repeating myself, unless they want to enshrine it in the TOS, simply offering vague references to members of staff finding some comments hurtful in an interview only a tiny proportion of this community will even be aware of, isn't going to achieve much. They would be better served either tightening up the TOS or training their staff on the matter.There's a big distinction between venting your disappointment, or annoyances and just electing to take the stand of attacking both the community and/or the developers. It's also quite glaringly the absolute worst thing you can do for yourself, the developers and the community you're apart of. Inflammatory remarks, regardless of whether constructive will just get ignored because they serve no purpose whatsoever. I'm pretty sure the majority of the community is of the appropriate age where this should be something seemingly obvious.
An echo chamber will only occur if their purpose is to very selectively listen to feedback, which I'm pretty sure is not the case. But whilst we're on this final section though. Arguably there is already a level of echo chambering going on within the community. Taking into account that in many cases views opposing are either met with nonsensical remarks such as "Find a new game", or "White Knight." These levels of remarks serve no other purpose than to attempt to undermine an argument. - Arguably in this respect, some of the community are already in the state where they're unintentionally creating this environment.
What is not a great situation is to create and entertain the notion that your disappointment, or disapproval in a product gives a token to be disrespectful and rude with your criticisms.
