PoE League Starter, Melee, Mapping builds

Pob fork: Disclaimer: I only play solo/with IRL friends, so this is technically SSF. I don't give a fuck about meta, I play to have fun. I league started with this build in mind and created it as I went. So, this is honestly my very first self-made build. So far so good, both the clear and single target feel good. I stumbled upon the combination of Sniper's Mark (spellslinger) + Pierce. You never have to think about what target is marked due to the fact that Marks are no longer a namelock skill. It also works beautifully because of how Subprojectiles work now:

This is a CD Bleed Sunder Slayer (May swap to EQ and remove CD if Sunder feels terrible for league content) The idea here is to be the position of the build before reaching red maps and attaining any BiS gear. It is super minimal but any tree optimizations or ideas to improve it are welcomed Looking very strong dps wise on t4 phys karui chopper w/o elder mod and should be decently tanky with an easily attainable 200% life on tree. Should be able to min max with clusters, BiS gear, elder mod, and timeless jewel into 10mil+ dama

league started with this build, started off using stuff like terminus est and praxis ring for free mana cyclone. got to red maps with essentially no gear, just rando rares. at which point i bought better swords etc. been self crafting a lot with the seeds and have pretty much min max'd most of my gear now. doing a double curse on hit with invuln + assassin's mark, the build is pretty well rounded, tanky, decent map clear speed, and very high dps for bosses, just incorporated some cluster jewels after the buff since they are relatively easy to obtain. pob has my old gear and non cluster jewe

PoB: So the idea is to go Trickster to make flicker free, and then to go MoM to take advantage of that defensively. I am doing this rather than Terminus Est Crit Flicker because I'm a hipster I guess? I've started every league since Breach with Oro's flicker, and I know it is quite solid for everything up to and including yellow maps, which is all I really need for a league starter anyway. Any suggestions for improving the build? Don't pay too much attention to the gear, I was mostly just playing around with the new "sort by dps"
