Full STR WAR is nothing to write off.

I'm pretty sure BiS Warrior will have about 9k HP. While STR war with Grypho's can have up to 8.2

Full ilvl90 and Gryphonskin is 8365 with party buff and food. I get 517 VIT in this setup, but I'm a Wildwood Elezen, so you can get an extra +5 VIT on top of what I have.
