My first attempt was as Trickster with focus on Ignite. Ended up pretty bad. Then, I tried to split the focus between damage-on-hit and Ignite with Scion. Didn't work out either. So, I came to the conclusion that the ways we approach the new Burning Arrow are wrong and I tried a completely different approach. I focused on damage-on-hit, partially ignoring the Ignite part and only making sure that the enemy is ignited so that I can get the flat damage bonus. And it turned out to be good.

The build I tried this concept on though is not a regular Burning Arrow build. It's a miner build with Blastchain Mine as Saboteur. And it seems pretty good. I focused on crit with Marylene's Fallacy along with taking full advantage of Born in Shadows and Explosives Expert and I added Herald of Ash for better clear due to the absence of Proliferation. The build has also decent defenses -around 6800 EHP and decent evade + Ghost Dance- and boss damage looks good. I'm tempted to try it as my second character this league, although that is one of a few builds competing for that spot, not to mention I'm far from done with my first character.

Anyway, here's my pob for whomever wants to take a look:
