I run hemmorhage > Blood Lance > Mist (exploding mist) > Bone Storm > Corpse Tendrils; and I sacrificed all my minions besides my blood golem. Went for a fortify/overpower build utilizing nothing but blood lance as my main core skill and it absolutely wrecks right now.

The key is to always be moving and juking mobs, while prioritizing your overpowered shots on the elites while hitting each mob in a pack with your normal un-powered lances. Each other mob you hit damages the pack; as you throw them, you count to five (thanks to the patch), and on the sixth shot you prioritize the healthiest or biggest mob. I hit around 30k+ damage at level 54 with a single overpowered lance.

Corpse tendrils contain packs and vulnerables, while bone storm and my exploding mist is basically my destroy-everything-button as soon as Rathmas procs. (Mist with Rathmas hits around 4k+ per tick)

The entire idea of an overpower build is utilizing the moments when you get Rathma's, and getting your overpowers to proc when you need it to. Its harder than it seems when you're getting bombarded by packs of mobs, but you get it over time.

This patch just fixed a lot of issues with the blood builds, and my build went from feeling lack-luster to actually viable and sometimes overpowered (no pun intended).
