Not OP so not mandatory. Sub par overall dps so skipable. Usefulness improved so that the dps loss isn't that much of a trouble.
Except then they're worthless in party content and either worthless or mandatory in raids. It has been tried before and has failed.

That said, bard is a DPS with cooldowns and utility, not really "support".
