Why the move delay?

Has anyone else noticed that when clicking on the ground it takes a short time (maybe 150 ms or so) until the character actually starts moving.

I'm not talking about lag/latency. I'm talking about a consistent delay that only applies to movement (skills trigger immediately) and my latency is only 27 ms and I have 80 fps btw.

In Diablo 3 when I click on the ground the character starts moving immediately.

I wonder why this delay was in implemented in PoE. To me it feels a bit clunky and I don't see a reason for why this should exist.
