I'm of the opinion the game should be more communicative about what stats mean. Critical Hit isn't just crit chance, it's crit multiplier for instance, and based on the one number we get it's hard to tell how it affects either of those statistics. Statistics like Determination and Tenacity are especially bad: "This is a stat that just increases everything!"

To a layman, this sounds like the best stat ever. "Why wouldn't I stack Tenacity, it says it increases everything and I take less damage and get healed more!" It can be a bit of a noob trap, and noob traps aren't what XIV needs really. I don't agree that knowing what these statistics mean could break the game, but that's also because I can't envision how knowing stat breakpoints (which can even now be datamined as I've been told) could break the game.
