Have you actually read Snyder's Batman run? its not a rehash and it certainly isnt a bad run.
Also some good New 52 series: Aquaman, Gotham Acadamy, Earth 2, Grayson, Multiversity

he had forgotten everything, Alfred was filling him in on who he was but decided not to tell him that he became batman because he could not bear denying bruce a chance at a normal and happy life

Really? I personally thought that Riddler never seemed to be especially enjoy mudering people but rather he was getting his kicks from showing off how brilliant he was, the whole scenario of zero year was set up so that he could see how smart batman really was, he refused to accept a fortune from the US government…

It is a canon thing and is brought up by several characters, in the Grayson series Midnighter says he could recognise him by his ass alone.

Harley has low end superhuman strength, she has the fighting ability and intellect to go toe to toe with batman, Captain Boomerang uses trick boomerangs (razor, explosive, remote control etc) to level the playing field and Simon Baz carries a gun as a backup in case his ring runs out of power.

but it was accidental, he got catapulted through time, secondly flashpoint was the first time he had ever affected reality in a major way and even then he had no way of knowing that things wouldnt go back to the way they were
