Currently, as many people have already said, the variable with the most oomph the current calculations is level difference.

If anything, this is what needs major revamping. the thought of the current formulae in a PvP setting is a nightmare to me. if you're not level 50, prepare to get WTFpwned.

the stats themselves i think are fine. i think the big problem right now is the dLVL in the formuae.

with the way damage is currently done, almost all damage is done via WSs and abilities. auto attack, while nice, doesn't really play that big a role. Also because the general rule is damage=enmity everyone should really be gearing for maximum damage. IE: everyone should be gearing for WS and capping their main stats. CNJ being the obvious exception, but they are still pretty straightforward: enhancing potency and healing potency. (MND and VIT)
