If you go back and look at the puzzles that Eladrin set out for us, the Pale Master's Necrotic Touch mechanic is exactly like the Warlock's Eldritch Blast. At will, no cost, enhancements apply, and it's a ranged effect. They have added all the required mechanics for the class to work and it would make sense that it is the next player class.
That said, if I'm right, it is severely disappointing. It provides the least-different playstyle options for players. It is a very weak class in general, and one that is best done in a true role-playing environment. I played one myself in a PnP Eberron campaign for about a year and it was great fun. However, it was by far the weakest class in our group, and that wasn't due to how it was built, it was just the nature of the class.
Options are great, don't get me wrong. But I'm tired of Turbine picking the low hanging citrus fruit. I want apples - not more oranges/grapefruit/tangelos.
