Please bare with me!
I think there is a Huge Gap between the feedback and the final game. Developers always follow the feedback of previous title and then they think they solve the problems and that can make players happy, but when the final game comes out and then it shows that's not what players want.
So, why don't you change the Develop Process?
Maybe you are worried about the ideas will be imitated or be stolen, but hey there is not much developers making RTS games now a day, so I think you don't worried about it too much.
I think the biggest part is Players part.
Players have to be very patient and don't put too much expectation on it, because the develop process is very long and there is a possibility of Cancelling.
And there is another problem, the Representative issue. There are so few people to join the discussion of forum and how do we know they are majority or not? But I think it's solve-able issue, because there are models of DOW1, DOW2 and DOW3 and we can more easy to know which one do more players like.
Now what should we do? I think Relic can make a Poll List to let players to vote which thing has the top priority to solve and then players can make discussions and then vote. After voting players have to respect the result.
To do so, Relic can know what they should do next and players can know it too and moreover it's a "Two-way communication" that can decrease the risk of bad decision.
Well, I just hope Relic can hold on longer.
Thanks for reading.
