Flame Trooper Warbringer

Here is the link to my build: https://poe2.ninja/builds/dawn/character/blobdog-7832/Pumpyrumps

I was looking for feedback, advice, or other ways to improve it. My equipment is good, could be better, but it currently works well.

How it works offense: Incinerate for primary damage, cast on ignite - arc.

Incinerate at full power does 17k calc dmg, arc is there for adding shock and doing some additional map clear dmg. Everything is ignited, all the time. In fact I might come down on my chance to ignite.

While the damage numbers seem small compared to "15 billion dmg LS build", it is the combination of incinerate, ignite, arc, shock, and burning ground that add up the damage.

How it works defense: 1500hp, 2100es, block 66% (warbringer all block with no raise shield). My only issue has been with the +% stun modifier on maps, as it allows mobs to break my channeling. Currently working in improving stun threshold.

Things that I have tried:
Shield with cast on block - not worth the damage loss of chernoborg shield, also inconsistent build up of energy.
Support gem that increases dmg after movement of 2m - does not work on channeling skills, or at least not incinerate (unless the calc in game is wrong)

Things I am working toward:
last accension - nothing exciting to get really so haven't messed with it. Perhaps getting the armor break on hit would be beneficial, but seems meh.

Passive tree - take overexposure and unstoppable barrier by using the tree rather than the diamond to free up a gem slot.

Well, I learned the first thing that was not working right.

Arc cannot apply shock, so will swap that for spark I guess.
