Slotting iLvl70 Crafting Gear - Which Materia?

[Ramsey]

Curious for those using iLvl70 crafted gear what they've slotted and why?

Trolling around on the Coil thread and then stalking people on Lodestone the only FC I could find using crafted gear heavily was BG, and they were all loading crit into their tank's armor.

I'm assuming this was not necessary for threat, but that they simply discerned that downing encounters faster from crit would be more beneficial? Most of these tanks were also Paladins I might add.

I have a hard time justifying crit myself, but I'd love to have people present their cases for slotting different materia.

I myself am leaning towards DEX, math on Dancing Mad seems to indicate about a 2% mitigation gain on 15 DEX (through parry and block rate increases), I could easily slot over 100 DEX over an entire set, or over 15% mitigation.

The other arguments are of course, crit, or (on eligible pieces) parry & determination.

Edit: Math indicates 4.7 Tier 4 acc materias will be needed to hit ACC cap of 470 for the coil. But that still leaves over a dozen unaccounted for open slots and forbidden meld opportunities.
