Coil isn't content that is needed to progress. It has some story elements, but it's difficult content that is intended for those who are willing to put in the time and effort to build a static with people who are goal oriented and like-minded. The fact is, this is the only hardcore content in the game currently and by nerfing it, is really taking away the rewards and pride of those who really earned it. Its not like this content is required to progress in the rest of the game.
