The Question to me is...why does anybody ever lock-on to any mob in this game at any time anyway O.o
It limits your movement(can't walk into the mob), you can only strafe...the whole controls are just stupid while being locked-on the target. Not to mention there is literally zero reason to do it at any time...so yeah...they could just not fix it at all and I wouldn't care.

Now...the camera not going back to it's initial distance after it close up cause of the surroundings or anything...that shit is messed up and that's gonna be fixed in 2.1...so yeah...they prioritize the right things at least.
