i never got why batman is in the JL especially in the new 52. The guy loves to be alone and work alone, its always weird to see him up in the watchtower chilling with the rest of the group. its probably like this because geoff is a f***ing idiot when it comes to writing bats.
They need him to be a part time member, so he can chill in his batcave more than the stupid watchtower. have him in the JL comics as much as you want but they should make it clear he is a part timer. just my opinion.
