You don't NEED a nin to tank fenrir :P
We did just fine with a WAR/NIN....well about as fine as 5 people who were fighting him for the first time can do :) The 6th was the WAR/NIN who was jp, and had defeated Fenrir before.
If you are going and would like my help, let me know > 71WHM. I'd be willing to get some spiffy items.
If not, then my advice is to have a BRD, the more life the BRD has the better. 2 hour dark carol at 1/2 life (tricky to do since you have to time it between his dispelling move, and his 2 hour ability) and for the mages to get to BFE before he uses the move, yet keep the tanks alive. If you survive the 2 hour, bust out your own 2 hours, and any items you have. Hi potions, elixers, wings, etc :P
