Is there any way to put BO ground abilities on your hotbar? I tried right-dragging and that just turns them red. They also aren't listed in the abilities list popup.
Not that I know of. In ground combat the BO's use thier own abilities. The only way to kind of control them is by turning them off until you want one to use the ability then turning it back on. This is why it turned red you with right clicked it.
Yeah, I know what the red means. You can also make them use an ability on demand by left-clicking it. I find that they don't use their abilities when I'd like them to, so I click on them a lot. I just want to hit a key on the keyboard instead of clicking.
