Even if it was before it doesn’t change anything the move roc started because Luffy acquired advanced form of haki adding CoC as well doesn’t change the fact that it’s still under Roc based moves.
That completely defeats the argument that Advanced Haki changes anything name though. Why would Luffy changed his move names with AdvCoA, but not again with AdvCoC?
Again, I've proven this already, both times "Roc" is used, it's an inflated fist. Both in Chapter 1000 and in 1036. In 1010, Luffy says "Red..." and then stops. You can see his fist is normal sized though. Its just Red Hawk because of this.
Again, let's wait until this chapter. If "Roc Gatling" is inflated fists like the others, then you'll see what i mean.
