I don't find the Khergit bow too bad for accuracy, though I don't get all that many kills (though that may be because I've only been playing a few days)
I do get alot of hits though. I played for a couple of hours before the new patches came in, but didn't get to use the bow so I can't really compare how it was to how it is now.
