Monk AC Target # for level 57+

[Nomand]

Hello all, hoping some experts could weigh in to clarify this for me. I remember back on live people would always tell ya hit your soft cap AC then focus on HP & primary Stats

Is there an AC value I need to hit as a monk on p99 or is there a confirmed soft cap for leather wearers? Does AGI get factored out and only focus on true AC number values off worn items only?

Thanks in advance!
