Negative effect? Lol. All powerup comes with negative effect for Luffy whereas Zoro has no such negative effects. Lol, g2,g3 losing life span. G4 losing haki and becoming deadweight for 10 minutes. No idea about G5 drawback yet.
Dude, I said in my original comment that I was talking about Wano specifically. And either way, none of the drawbacks you mentioned for Luffy come close to Enma literally sucking the life force out of Zoro if he's not careful. Even the whole "G2 drains Luffy's lifespan" was never touched upon again after he used it once
What negative effect Zoro got after Ashura and now after getting CoC? And even enma case, how is it negative effect when he is not using correctly his sword? He himself told he is not properly using it. Once he properly used it, boom he got CoC. And no negative effect. So please, stop talking about consequences.
Enma draining Zoro's haki is not about how "correctly" he uses it. It happens passively. All Zoro can do is get used to it better. And no, there is no consequence to Zoro using CoC but there is a consequence to Zoro using KoH mode...where Zoro said his sword was going to kill him if he kept it up much longer
Think about all of the boosts that the M3 have gotten in Wano:
Luffy:
-Ryuo
-ACoC
-DF Awakening (G5)
Zoro:
-Enma
-KoH/ACoC
*Also received the mink medicine
Sanji:
-Raid Suit
-Exoskeleton/IJ
Out of Luffy's boosts, Ryuo should not be considered an asspull. But if you want to consider ACoC an asspull for Zoro, then you should also consider in an asspull for Luffy because it came out of nowhere after Luffy got hit really hard. Same thing for his DF awakening.
And yet, Luffy has spammed ACoC attacks without consequence and we have yet to see any consequences whatsoever for G5.
As for Sanji, the Raid Suit gave him access to free external power without any negative effects. So it is an asspull. The exoskeleton had the potential to give Sanji meaningful consequences but Oda scrapped them.
Now look at Zoro.
Enma constantly drains his haki and almost got him killed against King. Enma restricts Zoro's usage of KoH mode as well. Even if you wanna say Zoro getting ACoC was an asspull, at least there is some kind of tangible drawback to Enma. Even if you say the mink medicine was an asspull, at least Zoro paid the toll. Oda could've easily just had him take the medicine and go off on his merry way
You can say Zoro gets asspulls. Clearly he does. But I truly can't understand how you're managing to believe that Zoro is the "king of asspulls" and gets less consequences than Luffy or Sanji
