I'm sorry but Batwing was terribly written until Palmiotti got on it & turned it around... An even then he essentially had to replace literally every aspect of the book all at once.
"I found the setting an interesting change from all the big American cities that occupy too much space in super-hero comics for my taste."
You might have but it wasn't. There was literally no setting to it, there was not a seconds worth of effort put in to bringing the setting to life. They spent no time setting up the status quo of Batwings immediate environment. The entirety of Batwings Africa could be summed up thusly "A city with lots of corruption." That was the be all & end all of the effort put into the environment.
Add into that that the real Africa is actually substantially more interesting than the version we were presented with narratively & its a bit of a kick to the teeth.
"I felt the protagonist had many of Batman's cooler traits but avoided some of the things that put me off the character."
Again you'd be wrong: the writers did not bother to give him even the first bit of a personality. He was nothing more than a completely blank slate, a frame work of concept wires, lacking for any kind of substance.
An the same went for all of the supporting characters, the antagonist & the plot: They were all equally lacking in character or depth.
Add into that the terrible story telling techniques & the reused artwork and you end up with a book that is both technically disappointing & telling a dull story. If you enjoyed it, then good for you, but don't mistake it for having been good, because it was exceptionally mediocre across the board.
