It may be boring, but it's better than Batman being a hassle to everyone else in-theater or getting killed.
I did watch the Justice League animated series, but I haven't read Morrison's run. I remember that sometimes, Batman might provide close air support with the Batwing, then it would get taken down because it doesn't have the proper defenses against whatever they're fighting, so one of his teammates would have to stop fighting the threat so they could rescue him. That's just pointless. By not simply staying at HQ and sending a drone to do the CAS work, he has just taken himself and the rescuing teammate out of the battle. It's completely pointless to me, and out of character. How many people might have died that the teammate could have rescue if Batman hadn't put himself in danger. If you can't take the heat, stay the hell out of the kitchen, and when you're Batman, you can't take the heat like Superman or Wonder Woman. By doing this, Batman is making the jobs of his JL teammates harder, not easier, by putting his ass in danger so that he needs to be rescued.
Many of his successful close-combat encounters without intervention required inconsistencies and/or ********, such as taking on Parademons that gave Superman a run for his money. This robs the whole event of the sense of danger that is the entire point.
This is why I believe if Batman is going to assist the JL in-theater, he needs some serious enhancement.
