Was gonna rant about how you could insta-kill the guy on the bridge by sneaking up on him, but that's been covered already.

The bosses in Deus Ex had a load of health as well and you couldn't sneak past any of them. You could run away from one of them and defeat another one before combat started by an alternate method (which required you to take the right choice in a sequence that happened much earlier, though). So your point that AP isn't a worthy spiritual Deus Ex successor because of forced bosses that can take a large amount of punishment simply doesn't hold up. Because Deus Ex did exactly the same thing.
You could kill both Navarre and Hermann by just talking to them. Wasn't easy, but the way was there. As for Simons, really, by then you could at least pack an auto shotgun or a rocket launcher, and he didn't have much hit points either (this coming from a guy who has finished Deus Ex 9 times, including once on Realistic with just pistols as my primary weapon skill).
I guess the only fault the developers have is that they didn't make the routes obvious enough. Which means the game wasn't accessible enough... wait, what? No, you know what, it's YOUR fault. Learn to play.
