VIT will scale with attack power, STR will scale but not as much

The only thing I am conerned about is that the bosses and mechanics in the next patch perhaps evolve around the 'full HP or dead' problem, which WoW had for a short while during WotLK (Patch 3.2, Crusaders' Coliseum).

A lot of FF14 progression mechanics and tank busters are tuned around having full HP of the previous max iLVL to survive. FCoB is an excellent example, you couldn't really survive a lot of stuff without being topped off with possibly a Succor beforehand. A3S as well, minus the tank buster part.

It's one of the ways they make gear checks in this game, having enough HP to survive, while simultaneously making higher gear make mistakes less damning.
