Sakurai was never gonna brand characters from the fan favourite game in the series as second class. Echoes only came out as a way to delude the people who whined that Dark Pit and Lucina "took" a spot in Smash 4, since they use different nomenclature. Nothing has changed about the ways clones are implemented, in reality.
The current clones are way closer to their source than the old Melee clones though. Probably because of balancing reasons.
First thing I will do is dart to the Tips section. Or maybe try and send an email?
