Just a little heads up, as prolly many people really want to know about that.

After doing some endgame stuff and/or fighting endgame related mobs, there is a definite choice on Stats now.

Put ALL your Attribute Points into Vitality!

Compared to STR and DEX, VIT is the one stat you really gonna need in Endgame. Stuff is hitting so hard that mitigation through STR, or raising Block/Parry Chance through DEX is neglectable cause of the amount of damage you get hit for. You need as much HP as you can get! This only applies to your Stat allocation though. Seing as any good WHM and/or SCH does use Stoneskin regularly in their healing cycle(and if you don't you're doing it wrong, period!!!), a bigger HP pool will benefit extra from this! So...raise your VIT. Based on meldable gear and their Stat Caps, there need to be more testing done to say for sure if VIT Materia is gonna be your first choice, since most of the times it is capped so low, that on HQ items you merely get +1 to +2 VIT out of a +7 Materia. I haven't checked out the Stat caps for let's say Parry for example, so it is not unlikely that you might wanna meld Parry, or maybe even Dex to your Gear, depending on which gives you greater benefit.

As I am SUPER busy in the game right now, I can't tell when I'm gonna do my next update on the guide. I implemented the rest of the GLA/PLD quests into it, haven't had a chance to do the WAR ones yet. But it shouldn't be too long before I will update the guide with Stat suggestions, macro guides and the rest of the class quests.
