Killed CR today with ~15x lvl 75's. Quite a fight, we originally tried with 12, but 10,000 needles spammage took us down. RRed and tried again with an extra 2 WHM's and 2 BLM's, DRK and myself making light, and NIN and SAM making Darkness. Took him down fairly easily.
If you let him spam his TP moves enough, any alliance with wipe. A few good stuns and BLM dmg vs. Melee dmg to minimize mob TP gain is suggested.
Bow did not drop, but I do like my title, very original ^^
