On: Bootstrap 3

Yeah, I agree. A good case-in-point is the new button groups.

Here is 2.3.2: http://getbootstrap.com/2.3.2/components.html#buttonGroups

And here are groups in 3: http://getbootstrap.com/components/#btn-groups

There _is_ a rollover state, but it doesn't really convey it is a button anymore.

And rollover doesn't work if you are mobile-first.
