I understand your fears, you seem to think that DCS:WH can hurt your community of pilots if its not online compatible with FC2. Maybe you are right. IDK. But when it comes to your expectations from the developer I think you are being a little bit unrealistic. You have to think about time, money, recources, will (maybe they are just sick and tired of working with the same lockon/fc stuff after so many years) and probably many other factors which I dont know about. Even a bug/stability patch for the main product itself can have a very high price, not to mention what you are suggesting (support for an old product). I would like to see ED stay in business. What would we do without them :) Look at the ghost of Falcon4, still here, fans never really let it rest in peace. Poor thing ;) I dont want that for EDs products, instead I want new products in regular intervals. I want fresh stuff that uses new technology.
Anyway I understand your fears about the online community. I wish you GL!
