I read the first arc for JLD and I didn't really care for it, though I do understand it improved. You probably could have Wonder Woman written well as a team leader among a collection of 'lesser' characters, but it just never seems to happen with characters like Superman or Batman.
I also really don't like League of One, half the book is just her brutalizing her friends (with bat-wank of course) and the other is her trying to kill a monster. The book very much plays up the 'Wonder Woman is a warrior' trope, I mean, she fights a dragon. Might as well describe call it Wonder Woman: Skyrim.
