The one JoL I've done since the update, we used 2 PLD/NINs and a PLD/RDM (me). I had hate for a majority of the fight, and it was only taken by a non-PLD once when a BLM started using AM2. You have to have a cure cheat setup for it to work. There's just no other way to generate a serious amount of CE. One of the PLD/NINs didn't have one, and she literally never had hate. I just used Flash whenever it was up, and Cure 3'd myself as often as I could. Whether you use /NIN or /RDM really is up to whether you want Stoneskin and extra MDB, or if you want to be able to blink away single target spells with Utsu and get a little extra CE from Ninjitsu spells. I don't think either one really gives you a strong advantage over the other.
