We've seen exoskeleton powers before. And zoro was given odens haki through enma. Enma had to give zoro a hint during his fight with king. It was basically zoro and enma in a 2v1 vs king.
And if i throw stones at my roof i can see them if i simply look up. You misquoted that platitude, friend.
- No, we have never seen that the exoskeleton allows you to heal, in fact we saw how Yonji needed a "special" machine. Let's also not forget how ridiculous it is for someone of Queen's level to barely use Armor Haki, not even on their sword. And let's also not forget how stupid Queen was for never taking Sanji seriously. Even getting lost with an Oiran.
- Enma does not give you any Haki, neither from Oden, nor from the King. That is a pathetic invention. The manga clearly tells you that Enma only drains the user's Haki and that it can backfire. So not everyone can use Enma and there is no such thing as 2 vs 1.In fact, the most damage Zoro takes is because of Enma. Yes, Enma is a help, but she is also a liability. In which case, it's a power up that is much more user dependent than the Raid Suit or Awakening. I don't think they are criticizable either, but when criticizing, Enma would be the last.
Some of you throw stones at your roof because you get so blinded by a character that when you criticize him, you don't realize that with the same yardstick, you are also doing even more damage to your favorite character.
Zoro was on the roof, he had a great performance, he was saved by the medicine Mink and he has Enma. Sanji was not there, he has a suit and his rival was quite pathetic and Luffy crowned himself as someone very close to the Yonko level and has the Nika Nika.
You have to accept it and be happy. None of, if...
