I never played a bard past 35 so this is mere guesswork

First of all KC is horrid, overcamped, pullers all tripping over each other looking for mobs etc. I wouldn't blame anyone for wanting to avoid the place.
For solo work:-
Emerald Jungle to kite (too low?)
Burning Woods (definitely not too low, but I know bards die there without knowing why... are there mobs that summon?)
Or if grouping, you'd be welcome in Sebilis - crowd control is highly valued and people want an ench/bard. You'll need to do your hunter/forager kills to get a key if you don't have one.
