Open PvP only and no oly?
Your jewels are pretty good, in best case I'd trade one earring for blessed antharas, or if you're rich enough, keep all 3 and change depending on situations (sometimes you don't need the mental from zaken, sometimes you do, depending on which tanks you're playing against), occasionally you'll wish you had a soul orfen so you may want that as well and equip them depending on the PvP.
CON dyes, PvE cutter OE'd +6 or higher is imo better than actual magic weapons, bonus points for good augment, reflect isn't actually very useful for you on healer on PvP.
dual class skills I'd get physical trait/HPx2, physical&mental trait or HP x4, it depends on what actually gives you most problems, you gotta see what gives you more difficulties on PvP. About the pdef trigger, from experience when I pick that I just get perma stun from daggers. I may try it again on this update, strong daggers are rare and many are rerolling on archer
