I think we do to some degree. We come here on the forums,etc and post opinions that influence the devs when they read them.
I think a vote would be pretty flawed though because voting doesn’t identify the people who understand the issue correctly - A lot of people may select a particular option for reasons such as nostalgia,desire of personal gain or conforming with established norms.
This could lead to a lot of feedback that is itself based on assumptions that are not true or don’t have the whole picture.
So if they did want to collect information to make this decision, they would be better served to ask people how they may feel about the impact of the decision and if they would appreciate that impact or be upset with it.
(ie, how progression would be affected by trade,etc)
So just to understand what decision they should make on this one topic they would probably need to do a more involved questionnaire and try to get a representative sample.
I do hope they intend to get some of this information from the community because while ultimately the D4 team will make the decision, they will be better served if they are informed on community desire.
