As to stripping Dick of his resources and relationships, I accepted it as being the frame of the story.
Why would you accept a story that simply doesn't fit that character, though? Dick Grayson is not a loner - he is, in fact, the most opposite thing to a loner that you can get - so casting him in a story that necessarily requires him to be a loner is SIMPLY WRONG, and everything that follows as a result of that will AUTOMATICALLY be invalid.
"This is a story about a hero breaking down, and it's going to be grim and gritty and angsty"
And that story doesn't work for every character, and you cannot justify plugging a character into those circumstances who doesn't fit, or otherwise, you might as well be defending Joe Quesada's portrayal of Spider-Man and Mary Jane in "One More Day."
It wasn't about changing the nature of the character, merely their circumstances.
IT'S THE SAME DAMN THING. Past a certain point, the character's circumstances MUST flow from WHO THEY ARE, because otherwise, you're condoning stories in which the plot drives the character, rather than the other way around, and plot-driven writing pretty much instantly falls under my heading of Worst Writing Ever.
