Why 7.5%, why not 5% or 9%? Getting parried still means your attacks don't land. There's no difference between getting parried, dodged or missing! Every point of hit or exp rating increases your chance to land your attacks by the same amount until you hit the hard caps. There is no diminishing return until then. This means that 7.5% hit / 7.5% exp is equivalent to 5% hit and 10% exp.
So there is no soft cap whatsoever. Consequently, it's questionable to try and reforge/regem to hit the 7.5% expertise as precisely as possible.
It obviously makes little sense to shoot for 7.5% hit and 15% exp if your iLvl is 450 since you'd sacrifice to much other valuable stats.
I believe everyone should test what they feel comfortable with and adjust their values accordingly. But forget this arbitrary number. There are hard caps and everything else is personal preference.
