Frank Miller's Batman actually did trust his allies to be able to do their jobs (who shouldn't all be genuinely superfriends, since that's generic. All the characters should have their own individual personalities and opinions of Bruce and it's more interesting if they are not all best buddies). Remember Green Arrow and Robin in Dark Knight Returns, and Catgirl, the Atom, the Batboys, the Flash, Green Arrow, Plastic Man, Green Lantern and Superman in DK2. Batman actually did trust his allies to be able to do their jobs and Batman himself wasn't left useless. "Even though he can't leap tall buildings or throw cars around, he's smarter than any of them. A guy as smart and determined as Batman would use every resource at his disposal." - Frank Miller. http://archive.comicdom.gr/interviews.php?id=17&lang=en Not just in Frank Miller's Batman material. In the Justice League by Keith Giffen Batman is the leader and strategist. Very stern. In Keith Giffen's Justice League #1 Mister Miracle thinks to himself "It's pretty clear why Batman and Guy Gardner are at each others throats -- they're two of a kind -- and it's a kind I'm not too thrilled with!" In the JLA by Grant Morrison, Batman is the smartest. Plus, he is the chief strategist and problem solver. In JLA: Tower of Babel by Mark Waid shows Batman has devised ways to defeat all of the JLA. "It's all just psychology and charisma with Batman. Everyone is wary of him because he's hard as nails, smarter than a bag full of whips and he knows all their flaws and weaknesses. There are just some people in the world that you don't fuck with and Batman is one of them." - Grant Morrison. http://www.strange-haven.com/news/100304/news3.html "There's a healthy amount of paranoia in Batman. He knows how to defeat each one of [his teammates] in case something goes wrong. So with every relationship with all the others, as much as they might find areas that they can agree on or talk about, he always sees them as potential dangers. So that limits what he's capable of giving to them. He feels superior to every single one of them, because he basically knows he is. He's the aristocrat of the superheroes—he's been brought up with money and knows he's the most gifted human being on the planet. He's almost so arrogant it's unbelievable, but he's not going to throw his weight around. Despite the other members' fears and distrust, Batman realizes he's needed on the team. As the 'ultimate human,' he's the team's problem solver, something [that] humans do best. In a lot of situations, the team will come to Batman and ask, 'What the hell do we do?'" - Grant Morrison. http://jl.toonzone.net/batman/batman.htm Batman has to rely on his intellect to fight crime. He is the world's greatest detective. He is the scientist. He is the strategist. He is a natural leader. He is the smarter tactician. He is a natural leader. Batman needs that edge so he isn't redundant.
In the case of Anti-M, Batman could have Green Lantern destroy Anti-M. The power ring has been shown capable of accomplishing anything within the imagination of the ring bearer. Marv Wolfman's Crisis was merely padded with fluff. The Crisis on Infinite Earths could have ended in a single issue. Wolfman was stretching the story and providing excuses for extended uninspired slugfests, shock value and angst. The cracks in the Crisis facade grew ever wider. And "killing off" so many potentially good characters rather than making them strong, viable additions to the DC line-up was a cop-out. Any writer with half a brain can see the potential the characters have. The western hero Nighthawk for example. It is doubtful that many readers ever knew that character existed - so why bother to bring him back and kill him? If a character is unknown to most of your readers he's already dead to them anyway.
