The lack of oomph is a good way to put it. I guess the thing I am feeling is that while I like much of the traditional feeling of D&D in DDN, I am finding that 4th ed changed my expectations of what makes a good RPG. Things like action points, utility abilities, encounter style powers and pacing, attacks that target defenses other than AC, wizard rolling all attacks etc are not optional add ones for me anymore. They (plus interesting monsters) are that oomph - for me. But I cant help recognize the tensions between these and the lean quick nature of pre 3rd ed D&D.
