The only one I have experience with is the one in Kaladim, which gives good EXP for like level 1-5 or so but not so much after that. I wouldn't expect any bone chip quest to give much more than that. In general, I would avoid bone chip quests and sell bone chips instead for 5-10pp a stack as long as you're not swimming in money. As a warrior, you could definitely use all the pp you can get, unless you're already well-twinked.
