Bard's Ult duration

We've had those times on Bard when ulting is the right thing to do, but you might hit ally or 2 and they COULD get out or better prepare thmselves afterwards if they weren't stasis just as long as the enemy team. How about instead of 2.5 secs on allies, it only lasts 1.5-2 secs and still 2.5 on enemies, that way allies hit by Bard's ult get out early so they can re-position into a better fight, or actually get away.
