No. Think of it like this: The thrill is breaking down an encounter like it's 4 bosses instead of 1. Each boss has several phases and to get passed one of those phases is an accomplishment. The thrill is getting to see the content at a slower pace, in essence, so you give the developers time to create more content. One time is enough for me, but I hate being able to consume the content in no time at all and waiting months for new content to come.
I have not once mentioned skill, yet people think I'm some sort of elitist for wanting the content to be gated by difficulty. What's up with that?
