@Darth:
A) The fact they were not in fact made up on a fly was already brought up, and I acknowledged it. So yeah, you got ninja'd on that one.
B) I would really much like to see them making an impact on New World.
Yeah I saw I was ninjaed, saw it a few posts after replying yours xD, I only enter to the forum from time to time, so it was bound to happen…I wanted to clarify it just in case =P.
I would say you will be loving the sotry once Drake starts to get developed, since we are bound to have a flashback that will explain why he defected the marines...We will probably see him interacting with the Akainu, Sengoku, Garp, Kizaru, Aokiji, Smoker,Hina...That flashback will probably be all (Or almost all of it) about the marines. I would say that will be the closest to the Marines Arc you proposed on the other thread xD.
And well, Kid and Law will have the bigest impact (Aside from Luffy and Teach), but the other will be having importance...As I told, Drake's and Bonney's flashbacks are things I am already expecting.

@DARK_RITUAL:
Right from the first time Law got introduced I knew he was gonna be a friend of luffys, he won't be Luffy's enemy.
Then when Law, Kidd and Luffy came out to fight that scene sealed my speculation.
Law was talking to luffy with respect(probably respecting luffy for being a fellow "D") while at the same time he was telling Kidd he's gonna kill him. And yeah Kidd was arrogant to the two.
Right now, it's pretty difficult to picture it, since Law and Luffy allied in order to defeat a Yonkou. But unlike other of Luffy's allies, we know that Law is aiming for One Piece and PK. In fact, we have been reminded twice (One of this two times by Luffy himself) that "Ok, we are good from now until we defeat Kaidou, but after that we will part ways and we will be rivals again". I am pretty confident they will have a fight near the end of the manga.
I will agree that Luffy won't be figthing Torao out of anger, more like just because they are rivals aiming for the same objective, which by any ways means they wont be giving their best against each other. Shanks would be a similar case: He is Luffy's mentor/friend, but there is no doubt that Luffy is eager to fight him (Though I am afraid Teach will not be allowing this since he will probably be geting Shanks and Killing him before Luffy even meet him again…).
Kid will be exactly the same as Law in my opinion. In fact, I am pretty confident that him and his alliance will be appearing in Zou, and I see them (Kid, Appo and Hawkins) maybe allying with Luffy and Law in order to get the Yonkou's head (As far as we know, Kid alliance could be aiming Kaidou as well). Luffy will be liking him much to his annoyment, and in the end they will give it all. If I think that the 3 will have a fight at the same time it's because of their crewmates: Killer is a perfect matchup for Zoro, and Bepo for Sanji...Add Jean Bart, Shachi, Penguin, Heat and Wire and you already have matchups for all of the guys in the Strawhat Crew.
