Don't get me wrong, Dick Grayson is one of my favorite characters in DC and I absolutely loved him as Nightwing. The Battle for the Cowl is one of my favorite stories and with Bruce out of the picture, among the other candidates to become Batman, Dick seemed like the most logical choice to become the Dark Knight. 
However, it's been too long and I just can't see him as Batman anymore. I mean I loved Batman since i was a child and during this time I had always known the Bruce Wayne IS Batman and there can only be ONE Batman. When Dick first decided to become Batman he was reluctant of course but then Alfred told him to make the mantle his own. 
If Dick had used like another costume and called himself Batman I would have been okay with it but he's using the exact same costume (before Bruce returned). The only this he changed was adding a bat symbol to his belt and weapons which isn't much of a change.   
I mean, I didn't have a problem with Bucky Barnes becoming Captain America in Marvel. Sure I was annoyed a bit at first because to me Steve Rogers IS Captain America but in time Bucky grew on me. Maybe it's because Bucky travels a different path from Steve. Bucky uses a gun, a bionic arm giving him super strength and a new cool costume. Also, Bucky wearing the costume and carrying the shield has served some purpose. I mean he used to be the Winter Soldier, a cold blooded assassin who hurt a lot of people, but by becoming Captain America, he is redeeming himself and trying to do what he always wanted to do since WWII, serve his country and accomplish some good 
As for Dick, his only purpose in becoming Batman was basically to replace Bruce because Gotham still needs a Batman. I get that. I also get that Dick becoming Batman has marked a huge evolution in the character, he went from being Robin the Boy Wonder to a self-titled Nightwing to finally reach the rank of Batman. But you know, to become Batman, shouldn't he be at least a match for Bruce himself, and I think that a lot of people agree with me when I say that Dick is not on Bruce's level (yet). There's also one more thing that is bothering me about Dick is this 

he smiled because he was enjoying it, and I think it worked, as him smiling would lead  the criminals to believe that batman is starting to crack and he could lose it at any second. Give Dick his chance, he works as batman just many people realize bruce is batman, dick isnt he's just wearing the costume. And dicks stories are worth checking outm trust me on his defiantly worth it.

I like how Dick told Bruce he should smile more in Batman: The Return....that cracked me up xD

Dick is an awesome Batman.
 
@RedHoodJT:
Yeah, I think Bruce did admit it.
 
Remember Dick is trying be his own Batman.

Im glad they kept Dick as Gotham's Batman. I dont think I want him to stick around forever, but it is so good right now. I hope if he goes back to Nightwing he brings out his old school Nightwing suit.

" Dick is Batman, Bruce is THE Batman. Big difference. Everyone knows Dick can't hold a candle to Bruce as far as being the Dark Knight goes, but he's a great crime fighter and Batman in his own right. He's just not THE Batman. "

I like Dick as Batman

@The Dark Huntress: @Lance Uppercut:    @FadeToBlackBolt: That's why i was having trouble accepting Dick as Batman. I mean, Bruce comsiders Batman as his real identity while for Dick, the Batman is an Alternate Identity. This is one of the major differences between the two. Is this a good thing for the future of Batman? Isn't the Bruce Wayne/Batman identity issue a main part of the Batman's mythos? Having Dick as Batman has removed a major part of Batman's mythos.
@Supreme Marvel:
I gotta say, after seeing that scan i finally see why a lot of people like Dick as Batman as he is bringing a new direction to crime fighting by replacing the dark violent tone into a more fun one.
But you know as cool as this new tone is, when you think about Batman you always expect a dark tone. I mean the most famous Batman stories are actually the darkest and violent ones, like Killing Joke, the Dark Knight returns, Knightfall. These are seriously dark-toned and violent stories but i think all Batman fans agree that these are some of Bats' most powerful stories and with Dick taking a whole new direction in the Batstories, we kinda feel that something's wrong. Well i havent read a lot of Batman/Dick stories so i could be wrong, I'm actually enjoying the current Black Mirror story in Detective comics because it carries a dark tone.   

I actually forgot about Terry Mcguiness, Batman Beyond. I should have mentioned him in the topic. I actually like him as Bruce's replacement for many reasons.

First of all he is using a whole different costume with new powers. He has Dick's presonality and he is being guided by Bruce himself. And thirdly, this isn't in main continuity, it is a possible future (or maybe it will actually happen). I would have also enjoyed seeing a new Nightwing costume.

As for the Daiman/Jason issue i think Damian is a less lost Jason Todd. They were basically had the same features: they're both violent hotheads who like to do things their own way in order to achieve what they see as a greater good. The difference is, Jason became a villain because he wasn't saved by Batman. I'm not just talking about The Death in the Family story, I mean even when Jason was Robin, he was violent and Bruce didn't guide him well enough. As for Damian, he is being guided by Dick and Bruce because they don't want him to become another Jason Todd.  
Jason is also one of my favorite characters in DC and i think he was a really awesome Batman during Battle of the Cowl but Damian brought a new direction to Robin by possessing Jason's violent nature while introducing a sense of comedy that blends in with Dick's new Batman direction.
