I think they deserve to be rewarded for their work.
I hope FH will show everyone that they can take over BF2 too.
I say, more power to them. DC was and is a great mod despite what anyone's personal preferences dictate. Its played by the most people and has always been the leading edge. Weather or not I think DC's quality is worthy of official endorsement or not is another story.
Its a great mod, but they never really went above or beyond the standard gameplay. DC_Final should be a nice patch.
