If the hard - corers want something hard and rare then I propose a series of fights that take a long time to complete which a nice reward at the end. Something similar to gaining Captain in 11. I say make these fights all very hard, almost incompletable. In this way you will show your skill and get a reward in the end that you can be proud of. If it is done with a party then all the better. Then you must prove your worth and your groups worth at the same time by cooperation and timing and good skills. Claiming a mob, in my opinion, only shows you can claim it, not the ability of your character. Hard fights will earn respect when you win. Yes, I think hard fights over claiming Nm's is more worthy.
