I likle to drag certain reactive ablities to specific hotbar locations, instead of using the reactive ability key settings in options. This way I can choose exactly which ability I want for the hotbar slot, all classes are different and it works much better for me this way. The problem is, after I drag a reactive ability to the hotbar slot I want, many times it wont work. Tonight it was doing it to me and giving me the error "This ablity is not available until the proper reaction is triggered", even though I could see the same ability light up and ready to hit on the reactive hotbar...but it is greyed out on the hotbar slot I want to use it for.
