This build is completely broken in PvP. You can 1v7 with it. My advice is that if you must play warlock in PvP rather focus on a GM build until, hopefully, abyss is patched.
Most builds can do 1v7, it depends on player skill. But d2r tried to change this, like any modern game does.
At least they don't use live algorithms to mess with your damage/hitreg etc like online fps does. Because thats the biggest cancer online gaming has ever seen.
No wonder games like cod loose 60% of its current playerbase every year.
Wierd CS2 has so high numbers, because it exists there as well.
People that spray chest/random body hitareas notice less.
High KD/Winratio = strict SBMM
High headshot% / High risk-high reward setups = Live nerf of hitreg/damage/hitpoints/hitbox sizes/flinch/messing with projectiles etc...
