Do you ever hear something about getting stronger and having new powerups, or about abilities in new world beeing important?
Probably no since you still think current Luffy would get trouble against Doflamingo.
If Sanji beat up Queen after showing multiple new powerups in the fact the panel with Doffy doesn´t proof anything, since Sanji became on his own stronger and even get new powerups(RS+other new skills).
You still don´t understand the concept of Oda, dude working for arcs to make Luffy stronger with powerups, making him strong enough to take soon on a fucking Yonkou who could curbstomp Doffy. You would probably even argue in that way when Luffy beating Akainu and Sanji later a Admiral, do you would still come up with that Doffy panel?
