for your MH, OH, Chest, and Head Items, use Diamond to max the values of your Legend Affixes.
then for your MH, OH, Chest, Head, and Ring Items, take off 1 (one) Epic affix and then use Obsidian to max the values of your Crystal Affixes. (Obsidian can now be used to max Crystal Affixes, but you need one empty space on the Item to do it)
then put the Epic Affix back on each of your Items and use Fluorite to max the values of your Epic Affixes.
then Farm for Experience for your Eternal Fauna to max out the last 2 Epic Affixes.
this will improve your Build only a little bit.
I think you have too much Push the Limit. your choices are to take off the PtL on your Chest and put a something else there, or change your Eternal Divination of the Blessed to a Legend Divination. doing the second choice would mean taking an Epic affix off somewhere and putting a +10 Skulldraga, if you really need it beefed up that much.
the Build looks really good otherwise. if you think it isn’t doing well against current PVP Builds, then you might just need to look at what the other Builds have and see how you can change your weaknesses to strengths, maybe into a totally new Build. (unfortunately, I’m still learning my way with PVP, so the maxing out your affixes is the best advice I can give)
umm, is this Wizard part of a 2v2 PVP Team? because I don’t see any Bleed Chance or Blistering, so your Vampiric Touch Set can’t Heal you and the Ruptured Mythic can’t give you +50% damage to Bleeding enemies, unless your Teammate is causing enemies to Bleed.
