Timer for Scrolls

Today, My guild and I were really bored. We decided to go cap skills and get skill points. We bought a Scroll of Hero's Insight. Went to Copperhammer mines. And went to town on pwning monsters for madly good exp and skills. The only issue we had was, we bought a Scroll that lasted 5 minutes, but if you kill a boss within the 5 minutes, the time is recharged. We noticed that we were running around looking for bosses most of the time, not knowing when our timer would run out. We thought that if we could see how much time was left for the scroll, we would be at ease. I think this is a great idea that needs to be implemented.

I do agree it would be nice to have a timer on the scrolls, not sure how this could be implimented without cluttering the interface. Maybe when you higlight the buff you can see the timer.

EDIT: Ah we've got a combined post here. Check it out. Sounds like an update that Anet would consider.
