This actually made me laugh. Beyond this being incredibly stupid to actually be of worth to any tank looking to do these instance.

I prefer to have a more set based chart
CM/Prae: AF
WP: AF gear with level 45+ jewelry and ideally GC weapon
AK: AF gear with some WP gear where possible, rest same as WP
Ifrit: similar to WP maybe some lower
Garuda: AK/WP gear and at least GC weapon
Titan: AK/DL primal weapon

Of course my standards are pretty high and skill can easily trash half that list, and most people do actually have that much skill.
