To be perfectly honest, I didn't really have much of a problem with the DLC strategy in Awakening/Fates. Yeah if you're obsessed with getting everything you're gonna have a bad time, but most of the content wasn't that meaningful outside of the AU stories about the kids, who weren't particularly interesting characters anyway. I think I spent about $8 on both, just for the Radiant games fanservice and the Fates prequel story just to make sense of that crazy plot.
Echoes was definitely worse, but still done in the same "salad bar" vein where the story DLC was distinct from the cosmetic and fast-grind stuff, and I didn't feel my experience was lessened by foregoing any of it. Still, $8 for about four hours of side story content was pretty lame.
That being said, having everything in one bundle is much nicer overall, and I'm definitely much more likely to pick up an expansion pass at that price.
