There's
some discussion on other threads about this, but the whole faction system was revamped when Velious expansion came out. I would save your Bone Chips until then.

"NOTE: In original classic, once your faction was capped with Iksar Troopers, you were unable to raise it with anywhere else in Cabilis as they all became capped (even if you were at scowling). I'm not sure if it is this way currently on P99, but please be aware of the possibility. It was later fixed on live. "
