Dear Shadows,
Her Hawkshot having global range is an intended part of the rework. Ashe can store two charges of Hawkshot every 90/80/70/60/50 seconds which have global range, give vision along the way to their destination and give 5 seconds of vision in a 1000 unit radius at the final location. The static cooldown is about 5 seconds, gives standard sight ( will not show hidden/stealthed units ) and is considered a projectile for the abilities Unbreakable/Wind Wall. In the future you may want to check the LoL homepage for information regarding champion updates.
Hoping you have fun,
Mr. Beane.
Edit: Typo was fixed; an area in the third sentence originally read "will now show..." instead of "will not show..." in regards to Ashe's Hawkshot.
