Bards and high end solo farming at 60

[Qalu]

Ahoy! I never played a bard higher than 30 back on live. Since bards can never run oom, and can mez and self heal, given enough time can they solo high end loot targets in kunark like shm and enc can do? If not why not, is mez/self heal back to full/repeat not a reliable process on 50's named in dungeons?

Thanks for any bard insight!
