One of the main things needs to be maintaining her supporting cast. Writers would never think to completely ditch Lois, Jimmy and Perry every other writer so why does Wonder Woman's cast get shuffled every time? Then find one city and keep her in it. Superman has Metropolis, Batman has Gotham...even Aquaman, Flash, Green Lantern...they have all had a consistent city. Wonder Woman...I dont even know what her residence is right now.
There's got to be some consistency in her book from one year to the next.
As far as creative team...I would take Phil Jiminez back in a heart beat. Either pair him with a solid writer like Geoff or Gail Simone or give him a co-penciller like Xermanico or Jason Fabok.
