It's kind of funny you mention you Class & Paradox as both of those groups have very deep scene roots, back to the C=64 in fact. Paradox was one of the top Amiga cracking groups and Class was started by some guys from Prestige who were also active on the Amiga around 94-95.
Personally I don't think all that much has changed except for the size of the scene overall, the same old ragging still goes on, a similar proportion of bad cracks get released but the majority work well (those clone releases are a bit of a joke though). I'm probably not as cynical as some of the old-timers but that's only because sceners come and sceners go, lamers (i.e. me) are here for the long haul
