I've raided, not a lot mind you, but I've had some of the best experiences in CE HM, when after an hour of wiping, we took Crota down. It was such a good feeling. But no raid being included in HoW is a good thing. VoG and CE were so buggy and weren't fixed until months after their release. And if PoE is good, that's another piece of content they can release ALONGSIDE raids.
