Can Smash DLC be done right? If so, how?

for reference, PSASBR had 2characters+1 stage for $10. Thats with a roster of 20 to begin with, as ssb4 will have over 50 characters in this game.

And I think that's critically over priced. I've literally never seen a fighting game/party brawler do DLC right.
