I think harrisdevot is trying to make the point that, in the case of Maiden, when you avoid the "Blaze years" (or those non-Bruce albums, as another member recently called them), you're also avoiding/missing the musical output of Steve, Dave, Janick, & Nicko too. Put crudely, 80% of XF or VXI are by guys who are still in the band today. If you listen to them now, why would you ignore these albums where they contribute the lion's share in terms of parcticipation? Blaze was just one of five guys when he was in the band.
The point is applicable to the band (why would Steve, Dave, Janick & Nicko want to ignore their own output?) and to the fans.
