Nino, I believe, was the musician who did a lot of Vanguard's music. Healhammer or something similar; I feel like I remember him being a cleric in EQ. Anyway, yeah, Vanguard had pretty stellar music.
Healers in general (not sure if Shaman was a healer or not, I just remember Bloodmage/Disciple/Cleric) were silly overpowered while I was playing. I think it was an issue with a self buff and self spell that combo'd or something, but a cleric could be healing at full tilt and still out-DPS average/good dps on a lot of fights. I'd like to think the dudes I ran with were just badasses, but a healer that could reasonably tank as good as/better than equally geared actual tanks, heal like a champ, and out DPS even leveled/geared DPS was a bit much hah. It started to fall off towards the 50s (again, close to release) but they were incredibly powerful, even solo.
