I'd again like to point out this game wasn't made for you. It was made with the idea in mind to be a cash grab. Second, I don't know where this idea of Awakening pushing the story to the side came from, except for the fact that almost literally every FE game does this. Teenagers conquering the world may have been innovative at one time. But not so much now. Hundreds of these exist now. There are exceptions of course, as with anything, but for the most part, FE is a game series with horrible cliched stories with interesting characters and gameplay.
Second, being able to grind is not a criticism I usually accept for any product because the game doesn't force you to do it. That's a choice you made on your own, knowing full well what you were doing. Blame yourself. That's a criticism of you. If you think a game should tell you not to do something because you lack the strength to not use the riekling boxes, or even worse, the dlc you purchased seperately, twice knowing what it does, I really don't know what to say.

Again, that's how FE has been for the most part. That is a series, not an Awakening problem. As for the free-roaming map, it's hardly free-roaming. How exactly are the useless, gray circles distracting you from the active, red ones? You're making a much bigger deal out of something that means pretty much nothing in the grand scheme.
That being said, I'm not happy with some of ways, most of the ways, Awakening turned out, not because it ruined a series of flawless, peerless, strategy games with concise and concrete storytelling, that "makes me want to cry," but because FE is a good example of NIntendo product stagnation.
