I kind of agree with you there. If anybody deserves it, Dick does.
However, the way that I think they'll finally resolve this is that Dick is somehow too noble, cheerful and good to function as Batman. And that only Bruce has the grit, dedication and end-justifies-the-means savoir faire (all the time avoiding using guns unless faced by Darkseid) to be the Batman. However, I'm drawing a complete blank as to what Dick will/should do after Bruce takes over the Bat-mantle again.
Unless they kill Dick! (Which would suck majorly!)I hope Grant Morrison's overall plan doesn't mean that Batman must not be allowed to have "friends" - so all the Robins have to die so that we can have a Frank-Milleresque Batman...
