Hmm... Not really. Whenever he happens to get more screentime, it feels like there's more to him than sleeping, training to become the strongest swordsman, and getting lost. However, when he does get as little time as during this arc, since this is about the lost kingdom and the people relavant to it, he's exactly as 1D as he is in reality. His backstory isn't really any deeper than that either, compared to the likes of Nami, Robin, or Tony, for example. Not to mention Luffy who's got the D, knows lots of great men, both dead and alive, and is the figurehead in general.
Nothing changes the fact Zoro is my favourite character of the bunch, though. I don't dislike focused characters. I also like the very rare moments when he decides to act like a vice-captain.
