Dagallon's Purifier -- First attempt at a theorycrafted build

Hello, all. I’ve been playing this game for awhile and just now decided to join the forums to seek advice on a build I’ve been planning.

Here’s the link to the build. Don’t have any image links, sorry.

What I should be going for here is pretty obvious – use Fire Strike to proc Bursting Round and Storm Spread, with Mortar Trap as a backup tool for when I’m surrounded. Word of Pain is for additional crowd control, Word of Renewal is a “panic button” skill, and the passives are there either to boost damage or provide additional survivability. With maxed-out resistances, three devotion combat procs, and four devotion on-hit procs, I think I’ll have what I need to survive.

…Or will I? That’s where you come in. If there are any glaring issues with how I’ve set up the build, please tell me. I don’t know if my OA and DA are high enough, and it’s worth noting that the exact point values for skills is tentative and will be adjusted as I get far enough.

Is there any skill I’m overlooking? Based on what I’ve seen from the item listings on GrimTools, there is some decent synergy between what I have and skills like Storm Box of Elgoloth, Blackwater Cocktail, Grenado, and Stun Jacks. I opted not to take any of these and just focus on the basics; was this the correct choice?

EDIT: Added Flame Touched at Makk’s suggestion.

No flame touched?

Does seem like a glaring omission. Should max it. I’ll take some points out of the Fire Strike line and put them in there.

Thanks for that suggestion! Anyone else notice something?
