Call me crazy, but why do these share a cool down? They are not the same thing, albeit, they are somewhat of the same ability, but if the meaning is taking literally, then they are not, and therefore should NOT share a CD
I quote:
Sprint - Increases the character's run speed for a short time.
'Running is a method of terrestrial locomotion allowing humans (Naka Duskal) and other animals (we humble/better Dragons) to move rapidly on foot."
Acceleration - Increases the character's fly speed for a short time.
Flying - The act or process of flight.
Flight - Flight is the process by which an object moves (again, we humble Dragons), through an atmosphere (the air in the case of Istaria) or beyond it (as in the case of spaceflight) without direct support from any surface.
So it is obvious to this humble Helian that the difference is more than enough to remove the shared CD.
