I vote yes for changing how stats work. The problem is that you have to stack stats to see a difference. This is why people put their stat points into only 2 stats. It is also why AF gear is not viewed as equivalent to double meld, or in the very least better than single meld (like they said it would be), as AF gear increases multiple stats and not just one or two.

The other problem I see with stats is that there is very little need for stats outside of the class's primary damage stats (except PLD and WHM, maybe BRD); they need to make it so that all stats are useful to all classes/jobs.

Anyways, this is my 2 gil.
