I think BRDs should be a support class. That's it. They should introduce a new ranged damage class such as Marksmen, Ranger, etc. Bards have traditionally been a support role in games. I actually like the idea of four (4) class archetypes in MMOs and the only one I can think of that did it "right" was Rift. You have the standard tank, healer, and damage, then you have the "pure" support that brings unique utility to the table (such as current BRD songs).
