This Looks nasty, any advice how to go on?

ilvl 79 Im Spark stormweaver. %mana would be great, but the greater essence can roll crap damage recouped as Mana instead. With speed essence i can force castspeed, but its expensive and i dont really need castspeed one this. Int also nice but Attribute Essence can also give me dex or strengh which i also dont really need. Thats my thoughts in this one. Im pretty new to crafting, id like to see what you guys are thinking.

Sometimes i miss imprint🥲
