I understand the armor argument but for me it's more fundamental... What are Batman's limits? (One word out of you Christian Bale an it's a smack across the mouth!
)
It's the presentation of the character for me. Improbable wisdom is a part of the character. I get that. Genius intellect, the world's greatest detective, tactical acumen ect. I accept that but fans always go on about the appeal of Batman being that he is the mortal hero with limitations but then they also accept or want him to also be Tony Stark and Reed Richards combined or something.
Before BVS some fans on the Hype were going on about Batman making "solar drainers" to suck the solar energy out of Superman. This is a bit much for me in my conception of the character. Look... Tell me Batman is a genius and I accept that, but let's get into the reasonable (even given comic book super hero suspension of disbelief) specifics of that. Tell me that Batman is the world's best hand to hand fighter and that is fine. Tell me "He knows EVERY single form of martial arts" and that's kinda ludicrous. He can be the best fighter without knowing and mastering every system or style. He can be an expert in the fields of criminology, forensics, and be highly skilled in the various technologies that go along with that... But I can't see how that translates into Bruce also having Stark/Richards levels of knowledge of engineering and cutting edge physics that would allow him to build at will these plethora Iron Man type suits, or like day in the JUSTICE LORDS episode of JL where the Lords version of Batman is building interdimensional portals in the cave. I can accept him knowing how to service his equipment, maybe even having the expertise to modify weapon systems or the like, but building EVERYTHING from scratch? So he had time to travel the world and learn detective skills, and martial arts, and advanced engineering, and cutting edge physics and... Well you see what I mean. He's a genius but he has his realm of magisteria as it were. If you put him in a room with Wil Magnus he can't possibly be near the creator of the Metal Men's level of scientific knowledge when it comes to computer science and AI and robotics. Now this doesn't mean he's totally out of his depths when it comes to a wide array of fields. I am sure he has picked up computer science skills like encryption and hacking ect. as they are germane to his war on crime. But going toe to toe with a Lex Luthor on the subject? No. Sorry.
Batman's near Omnicience has gotten out of control. The powered suits are a symptom of this to my eyes. In interacting with other characters especially it goes overboard since it tends to be presented in a way that makes the other characters look like fools, incompetents or besides the point. It reeks of plot armor. Why do we need the protector of sector 2814 armed with the most powerful weapon in the universe when the omniscient guy with a belt and some boomerangs can solve the problem? This hurts the DC stable as a whole and I think it's done so for a long time. The issues with Silver Age Superman were no different, it's just now because of popularity those have transferred to the all knowing BatGod. He's supposed to be the vulnerable one, the mortal one, the one that (again given the limits of suspension of disbelief) has to struggle against the odds in a world of super humans. If he's Tony Stark/Reed Richards that can take out Sinestro with a boomerang... I don't know... It feels off and kinda cheap. My two cents.
