These discussions about Enma are tiring
give the raid suit to any character and it will make him stronger without training. To tame Enma Zoro needed to get stronger himself and he trained to control his haki better. Through his training with Enma he got stronger within 1 week and not immediately like Sanji with his Raid suit. Because of that Zoro said himself that when he can tame Enma he has become a stronger person , he hasn’t said that because of Enma he is stronger now. If you guys want to count something as an asspull and power up then talk about the raid suit first. It gives his owner strength and protection without training.
