What class needs a buff or nerf?

[Tsilyi]

I believe you mean these songs:
Song 1
Song 2
Song 3

Actually, as a bard main who enjoys playing bard the way it is now, I was kind of hoping this expansion would bring more bard support and more songs while making Machinist more of a pure dps ranged class instead of another support class. These could have been interesting ideas potentially for songs.
