Storm Vindicator 1-75 Build Guide:

Within this guide, I will not show armor setups, other than to add the base version of some MIs that you should farm, as this build is purely theorycraft and I dont have the actual progress builds.

1-20:
For the first few levels, we will spec into Word of Pain. We want to get the mastery bar to 10 and then dump points into Word of Pain and Word of Agony, while grabbing a few one pointers along the way. Level 10 should look something like this https://www.grimtools.com/calc/nZo03gzN
For the next few levels, we will continue down this path, ignoring our second mastery, and just sticking to Inquisitor. Word of Pain is a great AoE mob deleter at early level, so its best for this stage of the game. Still look for lightning and elemental gear at this stage, as you will be changing soon, and you need the lightning gear. Level 20 should look like this https://www.grimtools.com/calc/eZP8vQjZ

21-50:
For the next few levels, just put the points wherever, until you are level 25, where we will respec into the general build we will use until endgame. At 25 we become a totem build, and should look something like this https://www.grimtools.com/calc/JVl4popV
I included the farmable offhand, which you can just search online to find out where to get it. We should also start investing devotion points, as we should have about 10 or so.
By the time we are 40, we will have access to more MIs and be past the main campaign. Along the way there just build up your main focus skills like Raging Tempest, Stormcaller's Pact, Storm Box, and Deadly Aim. Those will get you the most damage and make the build really shine. By 50, your build should look like this https://www.grimtools.com/calc/DV9j1KaZ

51-75:
We will work on getting through elite, getting our inquisitor mastery bar up, and swapping our cap stone skill from Stormcaller's Pact to Aura of Censure, and we will cap Inquisitor Seal, which is basically our "god mode" skill. We lay it down and then step inside it to buff our defenses like crazy. We can later upgrade the second skill, Arcane Empowerment to make it so that enemies who step inside the circle take a lot more damage. At 75, we should look like this https://www.grimtools.com/calc/xZyXrMrV
