Dual mass flywheels are supposed to have smoother engagement at low RPM, like when taking off from a stop. I never really noticed much of a difference though between dual mass and traditional flywheels. I agree they are a solution in search of a problem. Hard to believe they can over complicate a manual transmission, but they did.
The failures do seem more common in higher torque cars such as TDi's and GTi's.
The Focus has a DMF too, and with the factory engine mounts you could drive it around and start off from a stop at very low rpms for 4 cyl. At light acceleration the fuel economy shift light gets you down to 1300-1400 rpm at times so that only works with a DMF. I think alot of people have a terrible habit of letting out the clutch hard without rev matching and I can see how the DMF can't take that for almost every shift forever.
