The change in patch 1.1.0 made Siphoning Strikes useless.

Copy/paste from reddit :

Currently, Siphoning Strikes gives every Critical Strike (yellow and orange damage numbers) 100% chance to heal for up to 3% of your max life, up to a certain number of times per cast, regardless of any other variables.

Now, every critical strike has up to a 70% chance of giving you that same heal. “Up to” 70% because of how Lucky Hit works.

Example: Shadow Step has 100% Lucky Hit chance, so every cast of Shadow Step that is a critical hit has a 70% chance of healing you.

Example 2: Flurry has a 10% Lucky Hit chance, so every Flurry hit that does critical damage (again, yellow/orange damage number) has a 7% chance of healing you (first it has 10% chance to lucky hit, then that “lucky hit” has a 70% chance to heal).

Say you have 33% crit strike chance, that means every hit of Flurry has only a 2.5% chance to heal you. So roughly 1 heal every 43 hits. Flurry strikes all enemies 4 times, so you have to be standing next to a minimum of 5 enemies in order for Flurry to guarantee one proc of the healing affect.

In short, Siphoning Strikes is now garbage. For moves that hit a lot of times, like Flurry, TB, Rapid Fire, etc., it is a massive nerf to sustainability.
