We're not talking about quickness, we're talking about Luffy's dodging ability.
Luffy doesn't have moves that are faster than Bagua, you are again confusing dodge/reaction ability with speed.
Oh yes he does have moves faster than bugua, in Gear 5, chapter 1046, he uses it on kaido.
Not just that but chapter 1037 Gear 2, he moves faster than thinder bugua.
To make matter worse, his Gesr 4 snakeman in chapter 1041, was so fast that it pished kaido to use FS. It is faster than thunder bugua.
You should think before postong.
