So most of us probably know what "class fantasy" is. It is mostly used in WoW so we probably should use the word "identity" here. It is what your class is supposed to do/feel and what makes it unique.

Bard's identity is supposed to be ranged dps with group buffs in form of songs. While buffing has never been the core of the job, it has always been a strong part of the job that makes it stand out. In 2.x and 3.x bards had their more traditional songs, sure, there were only 3 of them, but they were all relevant and they were strong part of the job's identity. In stomblood I think they nailed it, I think this is the best version of the bard, not only does it corporate the songs in a fun way to it's rotation, it also makes them buff your team. Despite all the basic songs having the same initial effect, troubadour makes the unique. Then you have foe's and battle voice on top of all the other support skills.

In 5.0 bard loses foe's, crit buff from songs and unique effects from troubadour and gets nothing new in terms of songs/support. In fact the basic songs are not really songs anymore, they have nothing to do with songs anymore, they don't buff your team in anyway, they might as well be shot weaponskills. Now your only song is battle voice, that's it really, troubadour is a copy paste skill that dancer and machinist also have. Why do this? Bard feels more like a ranger now.
