scion has a lot more damage potential and space for customization, but a 109 scion tree ended up with 6k hp and 300 regen with no hope of getting near 3,6k regen (leech tho) of my slayer build, which I suppose is stronger for this league around (given that slayer has enough dps to kill everything)

Considering the 20% cull, slayer tree has around 1,5m dps, 7k HP and the said super high leech regen. Scion on the other hand has a lot of points to spare, can grab cluster jewels near resolute technique and basically has all the physical damage nodes in templar/marauder area and all the ones near the shadow start (ascendant gladiator/trickster getting shadow start).

Didnt bother to simulate exsanguinate dps, but the pob i used for scion is this.

Dont think slayer is strong enough for a community share, its a personal project.
