I'm so lost - what should I support with Spark?

so far I have:


Pierce
Considered casting
Arcane tempo
Inspiration
acceleration

is there anything I can change up to add more dps? I'm level 69, and my spark DPS is 2900.

also, on orb of storm, I have:


persistent
cursing current
lasting shock
conduction

Anything I should change here?

I've only played a little bit of sparkmage (definitely not optimal gems either) but those seem reasonable. You probably want to solve mana regen through tree/gear so you can use a damage scalar instead of inspiration though. Would also strongly recommend looking into something like mana tempest. Once you have decent regen, you can pop tempest, cast a couple of shocks, and then walk out of the tempest to get mana back.

At the point you're at, I wouldn't necessarily expect you to be super pumping DPS yet. You mostly get there through archmage/mana stacking and gem levels which come with xp and gear upgrades.

Also, make sure you're using flame wall and keeping it up all the time. Projectiles get a huge damage increase by passing through a flame wall, especially at higher gem levels.
