I really think you guys are missing the point in blaming Jeff...
I really, really, really like Quantum Break and especially its gunfights but I can totally understand why you'd think otherwise. The game does a TERRIBLE job of actually ecnouraging you to use your powers. You spend such a long time just fighting regular enemies that using your powers is almost never really necessary. Ducking behind cover, "casting" a Time Stop here and there and shooting works just fine.
Since the battles are often few and far between, I can totally see how you'd never really get into the flow of things - because for some people, there are just not enough possibilities and not enough time to actually experiment with the powers you have. You get a new one and then don't use it for the next 15 minutes, so you can almost forget you had it in the first place. That's actually something that happened to me: Only at the end of the 4th act I realized I almost never used the shield since I played the game really defensively and thus, never really needed it when hiding behind cover. When I played through the game a second time I had an absolute blast with every single fight (having unlocked every power from the beginning helped, too) and it was fine the first time around, but I can totally understand why and how you'd never get to that point.
When you are first introduced to the game's mechanics, it teaches you that it's a cover shooter and that you should take cover in gunfights. And then it basically wants you to do the polar opposite, without ever telling you so. You have to go out of your way to ignore what the game teached you at the beginning and act like this is actually NOT a cover shooter, even though it still is a cover shooter.
Vanquish had similiar problems, in that it completely failed to teach the player how to engage with its mechanics. In my opinion there is absolutely no reason Quantum Break should have a cover system. It actively betrays what the whole gameplay is about.
