No they won't, because Oda won't do so, because there's no real character development here (inb4 flashbacks are character development)
I'd say that they've developed plenty, both Usopp, Brook, Nami and Chopper. But for the SH's who aren't in the monster trio (except for Franky who's in a league of his own) facing off VS a Shichibukai all by their lonesome must be pretty damn terrifying. Especially when they also know that they've picked a fight with one of the Yonko and that the Shichibukai that's coming to kill them is allied with another. I mean they know how strong their own captain is, imagine the horror for the "weak trio" when someone that is Luffy level or above's gunning for them.
Ya know that these "exaggerations" like crying, laughing, or doing or speaking anything funny, or whatever it may be are deliberates to create humour in the story?
Of course it will always stay, as long as the manga goes.
Or maybe it could just be the character "traits" . Let's take example Usopp..he's the lying, crying when action happen sniper of the Straw Hat pirates , but when it's time to fight even when he "runs away" he calculate everything then when a opportunity present itself he strikes at full force . Yes he's a crybaby (you can say) but that doesn't make any Straw Hat weak when it's time to protect something or fight .
I guess some people may not find crying and sobbing as entertaining as some. Exaggeration is always like a "norm" in many stories. hehe!
