When it comes to Dick, i agreed, i usually blame Morrison for that, but you could argue that the whole thing started with Devin Grayson's run, that being althought current Dick is more similar to his fanon version, he still isn't quite there. Tim has his own problems, but i don't think that it was being like his fanon version, if anything he became the opposite of that since the post-Lewis era. The New 52 version has his problems too, but it wasn't that either. Rebirth Tim is the most close that i had seen the characther to the Dixon and Grant days, self repairing buildings and bullet trains aside.The thing is just that even the writers start to write them more like the fanon version, than like their "canon version" (by "canon" I mean mostly the Wolfman and Dixon).
