I'm talking I Am the Night here, gadgets are vital to your survival in that mode.. Like I said, that's the way I believe the game was really meant to be played, not on Easy. But if we're just talking no counter tell and infinite retries, is that really bullshit-difficulty..? (I guess it depends on how good you are?) Because I mean you were talking about enemies attacking you one at a time and them being easy to read, well Hard mode plus no counter tells eliminates that and makes the game a lot more interesting I tell you (enemies attack you simultaneously a lot more on harder difficulties but that was still present on lower ones, they also won't hesitate to interrupt your counters, a detail you seem to have glazed over). You really should give it a shot if you never tried it.
E: Oh um, also to be clear I got the names mixed up, talking about Arkham Origins. >_> But I think you knew what I meant anyways since I'm pretty sure City didn't have the mode I'm talking about, not to mention City's combat isn't as tight as Origin's.

The game's not as simple as you make it out to be. :v You need to pummel to get those extra hits in between counters. It's like comparing Adventure mode to Fortress mode, different paradigms entirely.
Yet another good example of a player using gadgets tactically in order to win on I Am the Night:
