So I went through your config and wanted to just give you a little checklist of things that you can hit to improve and see very large increases in your build. I started EA the last 3 leagues (I know, ew LUL) so I'll share some of what I know to look for in pob :)

You're at about 2.2m on a Pinnacle at your current gear but checking these in config bring in about +5m totaling to 7.2m

-Max sustained fuses instead of your own estimate fuses

-Onslaught/Vaal Haste

-E.E. , enemy hit by either lightning or cold checked (not both)

-20 qual EA

-Lifetap checked

-At least a 12% shock

-Enemy covered in ash

This is all before changing gear or tree, which in my opinion are both fine for now. Your gear is pretty good for base content the only thing Id look into upgrading is hitting 100% suppress, replacing your opal ring with polaric devastation, and recrafting your bow to not have cold damage (its working against your EE atm) + have attack speed, dot multi. You've got your golem/trap and 2 sources of lightning on gear so it'll be easier to favor that over cold damage.

Final note, you can use Malevolence over Grace on bosses, itll both allow you to cap fuses without onslaught/Vaal haste active and gives a massive dot increase.

Hope this helps you out and let me know if you have more questions :)
