PoE Vaal Flicker Strike, Slayer builds

TLDR: 8~11M DPS full buffs (Totems, flasks), 2.5~3.5M without buffs, 6k+ life, 5~6k leech per second, stun immune, 72% suppress. I often see Oro's Sacrifice Flicker as being just a very budget and crappy version of Flicker Strike, so I wanted to see how far you can take it with moderate investment.
