Unfortunately it looks like your image failed. But judging by the url it looks like you were trying to show a pic of Mr. Freeze. And while I can understand where you'd be going with that, on the other side of the coin is the fact that he's the biggest example of what I'm talking about. The entire objective of the Freeze Fight is to exploit ALL of his weaknesses (especially if playing on hard or New Game +). Granted, you've gotta diversify your tactics in the sense that he always compensates after you take him down, but still, you're essentially pulling off a Flawless Victory on the guy by attacking his shortcomings. Against Penguin you just keep out of his line of sight until you circle around behind him and use the jammer on his freeze gun...then you fight Grundy and have to blow up those three electric things a bunch of times.
The Joker fight in AC is pretty much the only straight-up fight there is. Beat the crap out of the Joker, his gang, a one-armed mercenary, and a Titan thug. No weaknesses to exploit, just a good ol' fashioned brawl. I suppose technically the same could be said about the Ra's fight too, but that brings up the combat mechanic of flipping around, punching a guy and jumping over to the next in a free-flow combo...how could you do that with two people fighting against each other?
Like I said, I just don't see how they could pull it off very well. Either the enemy is so powerful that Batman has to use all of his cunning and to get a perfect victory because being spotted means getting his ass kicked (i.e. the Freeze Fight) or he's flying from one thug to the next in a massive combo, beating the piss out of everyone (i.e. the Joker Fight). Either way I don't understand how they could balance it out without changing some major mechanics of the game.
