R cooldown increased early, decreased late
This is just not true for ashe...
It's increased at Rank 1, increased at Rank 2, and the same at Rank 3. It's never decreased.
Cooldown: 80/70/60 ⇒ 100/80/60
Damn, missed this when reviewing my sections of the patch notes. Summary sentences are added pretty late (not by the designers, typically) so I guess I overlooked this. =[
