false. HP is an aesthetic, but does not mean you're going to be able to do your job effectively. If you want to ween yourself into the position of STR tank I would suggest going 15 VIT and 15 STR, and when you feel ready go with the full 30 STR. Hopefully this has provided you with some insight on how to spec your tank. Just remember, there is no wrong way to tank or gear yourself in FF14 - the game is incredibly balanced and centered around abilities more over than armor or stats, In my opinion at least.

Let me know how it works out for you!
Good luck!
