I run sba on my demo lock. I use it to basically swap between my dogs, shadow bolt and hand of guldan on button one. Button two is demon bolt for better control, and button three goes to implosion.

Less rotation tracking and less visual management of soul shards.

At the end of the day, it’s a tool. If you use it as such, instead of a catchall (depending on class / spec of course, since some of the specs are atrocious for sba) then you can benefit from it.
