would there be a combination

Recommended Top Tier Merit pts are:

WAR/NIN x 4(maybe MNK/NIN second choice)
RDM/WHM
BRD/NIN

Every other DD is second to those mentioned above, then probably PLD on the bottom heap. Some switch BRD for the WHM or something else, but basically every merit pt strives to be like the above for better or for worst. However you better have NIN sub, and if you like skillchains, you are out of luck as its just spamming.

Algol + Homam Corazza + Ethereal Earring + Triumph Earring + Warwolf Belt + Foragers Mantle + Rajas Ring + Flame Ring + Galliard Trousers + (for ws) Hecatomb cap, mittens, leggings = a not half bad DD PLD. And they can get setup even better, this is just off the top of my head. My ls has a lot of PLD, so many of them, not having the setup i mentioned above, come to events as pld/nin and have high dmg swords and DD gear from their Wars or w/e.

Yes, because the majority PLD out there can obtain and afford any of that stuff. -_-;

PLD/NIN with just high damage swords and a few pieces of DD gear still isn't that great. I try it and friends try it, it really doesn't compare.
