Does knowing not knowing, haveing df powers or not haveing them make it less likely that its a DF fruit? maybe in the end Luffy will be screwed out of the power of that specific DF but still be pirate king because In the end that doesnt matter. noone can crush his dream. There is allways a twist to everything in OP.
Yes it does matter. This is a story like I stated and would be rubbish if Luffy was totally screwed at the end. Thats just bad story telling.
And to my knowledge we dont even know if WB is heading towards raftel. We know Luffy wants to go there, but i havent seen anything about Whitebeards final destination (or Blackbeards for that matter). Correct me if im wrong.
Well according to Buggy, WB is the closest to OP, so that indicates that he is looking for OP. Secondly, in his fight with BB, Ace mentioned that he will make WB king. There is no point to this statement unless WB want's to be PK. So we can gather that WB wants to be PK and is looking for OP. Raftel is where "One Piece" is believed to be, and would be the logical choice to go look for it. We can speculate Raftel is difficult to reach because Roger was the first known person to reach there and in the 22 years since his death no one else has reached there (it could be a sky island, like FFA speculated, or a disappearing island that appears once every 25 years, who knows). Maybe these difficulties are what have prevented WB from reaching Raftel, and why he is still wandering the New World. I believe (pure speculation) that if OP was on any other island, someone would have stumbled upon it at one point in 22 years.
Im not convinced about this idea im just tossing it out there… but a Certificate seems rather odd to me... Pirates arent imo going to consider you the pirate king just because of a little pice of paper says "the holder of this document... bla bla etc"
Whitebeard is probably not considered the pirate king because the pirateking had everything: wealth, fame and power. If the rumored "OP" continues to elude him he can hardly claim to be the pirate king, can he?
To your other point, WB also possesses wealth fame and power, heck, most uber pirates do too (except probabaly BB, who appears to lack fame). Like I stated before, OP has to be something that sets the PK above the other uber pirates. Btw, I wasn't serious about the certificate thing, just said it is more likely than a df.
