Cloak and dagger mechanics?
Aim and turn using the right mouse button, use strafe movement with strafe/turn keys.
You don’t need to be exactly behind you have an 180 degree window from left side to right side to hit your backstab within.
If you have chill or cripple on you, it will always be hard to get behind in time.

In the options you need to turn off clipping, not the melee assist. I cant tell you where it is, or even what its actually called inside the options, but thats probably your problem.
Thanks for the replies. I think in this case it is in fact the melee assist, it stops me from moving through the mob. I turned it off, and it helps with this, we’ll see if it causes other problems.
