calcualte monster damage on me?

Side note: Is there any mention of equipment level in the dmg formulas? (Say, does a lvl 140 take more dmg for wearing a lvl 30 overall asides from the obvious def loss versus wearing their class's lvl 110 overall?)

I don't know about damage formulas, but yes, I am pretty sure one will take more damage wearing lower level armor. I remember I was training at zombies at the time when the patch with that update came. I don't remember exactly, but I think I definitely took more damage after the patch as a level 6x wearing the level 50 overall (I vaguely remember it as 8x damage before the patch then 14x damage after, though those numbers seem strange).
