Warrior Melds/Stats allocation

[Brian_]

STR = VIT > Crit > Det > SkS

That is assuming you meet the accuracy requirements for the content you are doing and the SkS requirements for a consistent 9 GCD Berserk window (which depends on your latency).

Melding STR / VIT is only an option on Fending / Slaying Necklace / Earring / Bracelet / Rings due to restrictions on main-state melding. Outside of some rare scenarios, you will want Fending accessories melded with STR.

When looking at an what to meld for Helm / Chest / Belt / Gloves / Boots / Main-hand / Off-hand, it depends on what stats are maxed. By default, all items will have one of their secondaries maxed. You can usually tell which it is by which secondary stat has a higher value. Looking back at the stat weights, if your piece does not have its crit secondary maxed, it makes the most sense to meld crit. If crit is maxed, it makes the most sense to meld det. If crit and det are maxed, you should meld SkS.

A small detail worth noting is that these are point to point comparisons. In the case of grade IV materia, because det materia were scaled based on 2.X stat weights, grade IV det materia only gives +6 det compared to the +9 SkS grade IV SkS materia gives. As such, despite det having a higher stat weight, it is better value to meld grade IV SkS materia because 9 SkS > 6 Det. While there is a downside to having too much SkS on other tanks due to TP issues, WAR doesn't have to worry about TP due to 0 TP GCDs and Equilibrium. But, if you intend on using the gear on multiple tank classes, you might want to factor this into your melding decisions.
