A bit late late to the fray, I know, but I want to speak.
Personally, I loved the DM's. Granted, their set designs were weak in places, and there could have been more figs, but I liked the fact that we finally had a proper evil faction. Yes, I know lots of people enjoy making their own bad guys instead, but up until 1993, there had never realyl been any enemies for the Crusaders etc. to fight. When the Dragon Masters arrived, I think it changed for the better.
As for the set, I've really explained it above, and the Wolfpack guy 0wns. It would have been nice to see a Black Knight or two squeezed in there, but the Dragon Masters are enough for me.
