But really Leviathan takes the cake,Bane has been hit(Knight Terrors,Arkham War,Talon) and miss(Batwoman,recent Batgirl issue),Riddler is up there as well based on Zero Year atleast,Wrath was cool too, Court of Owls were inflated and hyped.
There is no need for a reboot, The New 52 is only a few years old. They have to give it 10 - 15 years IMO. Why do alot of people hate the New 52?
10 years or 1 year,what difference does it make? the new-52 continuity is a clusterf*ck,a Zero Hour style clean up is gonna happen no matter what,it's the only thing DC is capable of,in a span of 25 years they've had 2 hard reboots and 2 soft reboots,company wide ofcourse. We'll get a soft reboot in 3 years,mark my words.
