Hi.
What about making a sprint clicky.
My thought would be a low level item (in the range of level 3-7) with 1 charge that gives 30% action boost to movement speed for 20 seconds like tier 1 of the enhancement sprint.
This item should be upgradeable to Epic and Legendary like other items are today.
The Epic vesion would give 2 charges with 40% action boost to movement speed for 20 seconds like the tier 2 of the enhancement sprint and the Legendary upgrade would give 3 charges with 50 % action boost to mevement speed for 20 seconds.
Why?
Well not all classees get sprint as a choice in enhancements trees and not all have or want to invest AP into sprint. With 99% of groups today (from my experience) beeing zergs this could help out not beeing a straggler and could help out for those that come in late to catch up.
Just a thought.
Best regards everyone.
