CC + focus on you = dedge. That's not a plus side of Chiten. Actually making it better for the opposing team since focusing is always better, and you're giving them an easy indicator.

Focus macros and keybinds would allow a WHM to sheep you just as quickly as a script would do it.
nothing is as fast as a script. I've seen skyshatter be stunned as a DRG falls from the sky resulting in a wasted LB.
