Good points made here.
IMO the biggest mistake made in the new52 was the 5 year timeline. I think dc basically shot themselves in the foot with that one. 4 Robins in 5 years supposedly? That's why Nightwing has no back history with Titans, Tim started the titans yadda yadda yadda. They forced their own hand into leaving Dick with nowhere to go.
I don't know (and don't know if we ever will know) what the original plan was for Dick post forever evil, but I feel (hope) that this is a very good way to deal with the mess made by dc.
As for all of the character traits listed for why Dick is the best choice to be Bruce's spy, (and the type of spy he most closely relates to) the one overlooked is that Batman trusts him more than anyone. Yes he has the looks, charisma, intelligence, and athletic skills. But he also has an incorruptible will and desire to help people no matter the personal cost. He is the only man Batman knows who can enter into this world,do the job, and come out the other side.
Tim couldn't, and Jason couldn't.
Dick can, and Dick will.
Even if this character change was because DC painted themselves into a corner, Dick is head and shoulders above the other choices, for me it's not even close!
Bruce fears spyral. The whole Spyral as a dangerous threat hasn't been played out yet, but once the series starts I'm very hopeful that Spyral is shown as a dangerous threat to everyone, and Bruce's fear of their reach is legitimate. Bruce's fear and how unsure he is of them, and his choice for Dick to infiltrate their ranks has maybe not been as fleshed out as one would hope yet, but when the series starts gaining steam, Dick will rise to the occasion and to the top ranks of the dc heroes!
I've finished this glass of koolaid, now can I have another?
