What should my materia be?

Meld strength on your accessories for sure. As everyone has said. It's the strongest option by far.

After the scaling was figured out it turns out tenacity can be pretty worthwhile. While not the absolute strongest choice for DPS it's actually not that far behind direct hit.
All in, offense and defense included, it's a really strong stat and I think I'll be favoring it on my left-side, especially at the beginning of a tier when my ilevel hasn't caught up. It's still going to make me do more damage and it'll also help the healers out. It's a small sacrifice to make vs. direct hit.

The reality is that the secondaries don't have an outsized impact on tanks. DH, Tenacity, Crit. Whatever, as long as you're melded up they're all going to be pretty close to one another.

But any serious raider will laugh at that.

I just thought I might point out but one of the people in this very thread saying tenacity is a good stat to meld is a very serious raider.
