ogre shaman on the bard diet?

[Grayskull]

Was just considering maybe going on the bard diet for a while on my ogre shaman, and I don't think the faction hits would really bother me, and maybe i could get my mayong mistmoore faction high enough to somehow make camping black dire easier for later? Is there any faction hits I should care about, or any good reason why I shouldn't kill some bards?
