Let me aim freely without lock-on (Maybe a setting option?)

It's really annoying. Even if you hold down shift the problem persists.
I've died several times because my monk continues walking in a different direction while using flurry skill (eventhough I use WASD movement) than where my mouse is aimed.
Please give us an option in settings to toggle lock-on off.

Shroud explains the problem really well here, time-stamped it for you:

Reviving this, it's causing me mad issues on my ranger.
