I imagine that the health bar system is only used for formal Tournament battles when, in all likelihood, the Team Leader can request a time-out to do so.

It isn't inconceivable that there might be a hands-free version of the scroll with an eyepiece (like a Google Glass) that is used in combat and has specialised software for that purpose. Heck, Glynda's glasses might be a hands-free Scroll that has the added advantage of adding to her 'badass scoolmarm' persona.
