Unfortunately I have only seen any back tracking and changes implemented when enough players have offered negative feedback. The option to turn off H/A and the HOF disaster.If you find that frustrated rants laced with negativity do not result in the outcome you want, maybe some supporting words of encouragement would be worth a try.
A lot of what you are observing now is frustration built up over time because the developers seem to go out of their way to not provide what their customers request or remove functionality without considering the consequences or maybe they just don't care. It is difficult to know because there isn't any direct communication.
HRC may not speak for all players and the vast majority do not even visit the forum but I have to say the ones I have discussed the developers actions with have all had a negative view of them and do not believe they listen or care about their customers. Especially GvG players who have experienced several changes that have had a negative effect on it. Changes that haven't actually achieved the published reason for implementing them.
