The defeat of Doffy and his crew will most definitely show the rest of the world how much stronger the Strawhats have become, bit of a shame that Sanji & co are not there as well but I expect Oda has plans for them elsewhere.
The fight with Doffy is not over yet and we will have to wait and see just how much damage that Red Hawk did, while I would love to see a solo steamroll of Doffy to really drive home Luffy's growth during the timeskip I suspect it is wishful thinking on my part.
We have seen how strong Luffy's attacks have become with COA making a big difference but I am more interested to see how well Luffy uses it in defense, I am wondering if maybe Luffy has multiple levels to his Hawk move, perhaps burning even hotter and becoming a White Hawk or Blue Hawk.
If the Red Hawk Luffy has just used is not enough to shut Doffy up, having used it at the start of the fight I expect Luffy has more up his sleeve.
Luffy will still fight alone against him. We have to remember this:
