PoE Ballista Totem, Pathfinder, Lightning builds

I've put together a bit of a PoB testing the new gem doing some Voltaxic poison weirdness - it seems to come out with pretty respectable DPS numbers but I'm not entirely sure about the build never having done a poison build before so I'm seeking some input from the reddits before committing to building the thing... The basic idea is to use pathfinder proliferate (testing tinctures but charms could be better) with the new LA sticky arrows gem to stack up pretty big poisons quickly and let them run through mobs with prolif rather than using pierce etc Interestingl

super super rough PoB (especially considering changes coming): 3.16 i'm gonna be making an MFinder just for the fun of it and so am having to build around all of the uniques. it's pretty restricting. there's almost no flat life or resistances on the gear (didn't want to put in some PoB ventors) and so am building around that with a super passive playstyle (bow and ballistas) and lots of jewels on the tree. but also damage itself has been a question for me, especially as i don't really trust my capacity to get an honest readout from PoB with all the moving part
