You seem to be under the impression that no matter how it's implemented people should be happy, which is ridiculous. Yes, people wanted tougher field mobs, and it may not have been implied every same second as that was suggested, but it's obvious when people want something to be tougher, they want equivalent reward from it. The Fates in the new areas are trash, many have established this. So what if they got tougher mobs? It doesn't mean jack shit if they are there just for being fancy dmg sponges.

And nerfing the Fates that are actually useful won't win any favors from anyone. They just need to actually make being in the new zones worth it.
