Slayer/Starforge/phys+chaos/life leech+bleed/Need Help pls

Hi, I'd like to get advice on this one. I probably don't get some mechanics cause i tought my dps would be much higher witch such wep and more dmg stacks.

My goal was to stack more dmg, life leech, bleed chance, chaos from phys, phys resist.
