character walks to cast

Playing mouse and Keyboard, I tried every option with box checked and unchecked "always attack without moving" in interface I tried unchecking and checking attack in place key stops move.

Every time I am slightly out of range my character walks forward to cast to be in range, most of the time to my demise, walking into packs or fire, or directly into a slam, its almost unplayable. Skills I am using I notice on the most are essence drain but it happens on contagion and others as well.

If this is a bug or if anyone knows a workaround or if I am doing something wrong let me know. Thanks.
