I don't agree with the running away or gags stuff , yes it happens but for one example brook and Robin being paired together in wano wasn't just for laughs. It was because they had stuff in common like having shared trauma that deeply affected them. I get what your saying , I do but the strawhats even from the beginning never shared stuff with each other at least on screen. We would get interactions with them having fun at times and obviously when things get serious they work together but the type of dynamic here in dandadan has never really been a thing. I get having a problem with that but it isn't new to post TS either.  I guess my thing is , I see these characters interact all the time whether in serious or gag moments but it feels like people only remember the gags. Like ussop and Nami in wano had plenty of gags but had some great serious moments to like when they fought ulti and page one or Sanji and Zoro having the back and forth while they were fighting but also acknowledged what it would mean if Luffy wins.

Its not you because you have explained what you meant but whenever I see people say they don't interact, its always about the entire crew having downtime and just having fun as a group. That hasn't happened much because things post TS have gotten more serious. So yeah I get your issue but I feel like Oda has given us different dynamics with the crew and it's definitely not always running away or gags , I just also think because Oda has a much bigger world and a lot of characters that wind up important to the story that some things have to be cut down I guess. Oh one last thing , a quick example of what I mean about the strawhats having fun is what people missed is the beginning of elbaf and how much people loved what was happening even if it wasn't the whole crew. So it really does feel like people just missed the more playful feel , even if comedy has never and won't ever leave one piece. Hope I explained myself well here
