How is this Balanced? (Bard)

[Koltik]

It's not like bard burst isn't obvious as hell and can be stun locked or you can cc them or los them or use carnal chill and many more things.

Cool. You can also do this vs every other DPS, the difference is that they don't even have the ability to kill you in half a second (MCH excluded, but that's another discussion).

Yeah those dps also don't become useless after using their burst and hit like a wet noodle for the next 90+ seconds. And DRG can pretty much do the same thing. So does machinist and it's way harder to see it coming or even prevent it.
