GB combat?

[medalofwhat]

hi, im hoping its something im doing wrong in the setup but the combat for my shammy while using GB is pretty bad. if i have more than one mob ill face one and kill it but he doesnt turn to kill whos attacking his back he just stands there and spams target must be in front of you.

any suggestions to clean up his combat to make farming easier? any and all info is welcome and appreciated ty in advance.

edit: i may have figured it out. hit character specific keybinds and reset it to default. thought i had reset them already:x
