BLM's I do agree with you on that part, they do not bring much utility other than their dmg alone. But saying SMN isn't bringing utility? Think your statement is a bit off there unfortunately. Indeed bard's have their 3 songs and batte voice along with a silence. SMN has Resseruction, eye for an eye, and the different combination between 3 Egis could be used in certain situations. They even bring a heal that I ofcourse know is not actively used, but they have it if the situation would require. Along with this you get the "Swiftcast" which basically makes you instaress, change to a titan egi if anything happens to go totally wrong and you need a quick support. Just want to point out that SMN does indeed have a lot of utility that's useful ( just thought about the skill "Virus" too as i typed hehe).
