PvP is a joke, you know. No one PvPs seriously nowadays and I have heard tales of The Feast that do not exactly make it good content. That said, there is existing content some people don't want to touch already (exs, savage, etc.), and are perfectly fine not doing so. The trend you speak of started ages ago.
So your logic is that because there aren't enough hardcore raiders that they shouldn't get worthy content. That, my friend, is false logic. If players don't have anything to strive for then they will get lazy and complacent and not try hard enough to get good enough to even attempt hardcore content. Coils Ultimate is a mountain to climb and while not everyone can climb it or reach the top it is still something to strive for. Furthermore, why punish good players with faceroll only content? If all content released is so easy everyone could do it and clear it then the game will get boring.
