G5 won't do much against them, advanced Conqueror's haki is the difference maker against Lunarians.
		
		
	 
 I don’t think so 
G5 may have dura neg with the weird Rubber phasing properties that were shown 
	
	
		
			 G5 without advanced Conqueror's is nowhere near a top tier, with him even having a matchup disadvantage against King.
		
		
	 
 Nowhere near? That’s a stretch 
G5 Luffy without CoC still has the speed to keep up with Kaido + Rubber phasing + he can use internal destruction 
It’s very powerful 
	
		
	
	
		
			Kaido would laugh at G5 without advanced Conqueror's haki and low diff him.
It is advanced Conqueror's haki that plays the key role in making Luffy a top tier, even though the gears do play the role of upping physical stats.
		
		
	 
 It’s what makes Luffy mid to high top tier 
Even without ACoC I’d say he’s still in/as close as you can get to the top tier realm 
He would definitely lose to Kaido but idk about low diff 
	
		
	
	
		
			It is humiliation for Zoro, cause it means he is low diff material for Luffy now. What even is his role in the crew then??
		
		
	 
 To be the 2nd strongest fighter 
That’s always been his role 
It’s not like he’s the only roleless Strawhat, all Usopp does is shoot
