I find it interesting that the only change the Crisis really caused with Batman was to turn Todd from cipher to creep. Other than that, he seems to have stayed outside it, and his entire history up to and including Dick remained more or less intact and precedes the Crisis. (Year One only filled in detail, and does anyone remember or care about Year Two?) I mean, compare what they did with Superman--Batman was mostly untouched, except to ruin bits and pieces here and there. Classic case of "If it ain't broke."
And Mike Barr had actually developed Jason well, so what was the point of that?
