There's more fanservice than the time before the timeskip, yes, but I think it's a bit stupid when you're only bashing the females of the crew. They're not the only ones who're showing more skin now - it's the same with Luffy, Zoro, and even Usopp. Our Strawhat captain has started to wear his shirt open, Zoro is now taking off clothes in battle, and Usopp shows off more muscle. The only difference between them and the girls is that the guys get more time to shine. And then again, with the exception of Usopp, the guys of the crew are more the fighter types. It could be that Oda wants to show that the Strawhats have more freedom now with loose clothes and all, but I don't know.
There has barely been a hundred chapters after the timeskip, and people are already complaining about the lack of spotlights for the females. It seems like people forget that both Nami and Robin only had one solo fight each before the timeskip. Nami had her moment with Kalifa of CP9, but nothing before or after that. Robin got the chance to fight during the Skypea arc, but nothing more after she joined the crew. In almost every single arc, the girls have always fought together with the other crewmates, just like they do now after the timeskip. Just be patient, and Oda will eventually give them more time to shine.
Now to the other discussion in this thread, about overused character traits. I think you're asking for too much if you want Zoro to suddenly get a sense of direction. Or if you expect Sanji to mature after spending two whole years on the island of transexuals. It's just who they are, and I personally don't think it's time for them to change just yet. There's still a decade's time for Oda to get the chance to develop their characters more. Like most people, I like their characters and don't want them to change, but maybe I'm just blind with character love.
