Incendiary Shot issues

I have tested Incendiary Shot for a while now and it very rarely set enemies on fire. I added Ignition Support to it and hoped it would help but its basically the same. Extremely rarely is an enemy ignited. Compared to Permafrost Bolts which actually freezes enemies often and feels useful.

Since PoE1 for the most part felt logical in how things interacted i thought Gas Grenade would ignite with Incendiary Shot, but it doesnt. You have to either throw a Explosive Grenade to ignite the gas or hope an enemy is set on fire with Incendiary Shot (which almost never happens). It would be logical that our Gas Grenades actually are ignited with Incendiary Shot. At least logically. Maybe balance wise it isnt? I dont know as an outsider, but i thought i'd mention it because it feels weird gameplay wise.

Thanks for reading & keep improving and tweaking the game! :)

I suffer the same problem. The skill already does shit damage, and it close-to-never ignite enemies.
A bug possibly?

Explosive Shot will do it.
