Can I get some context on the Blitzcrank changes?
Blitzcrank Overdrive (W) has received several changes: Duration reduced to 5 seconds from 8 seconds. Movement Speed % increased to 70/75/80/85/90% from 16/20/24/28/32%. Movement Speed bonus now decays over the duration of the buff. New Effect: When Overdrive ends, Blitzcrank's movement speed is slowed by 30% for 1.5 seconds.
I can see how this is a buff and at the same time nerf but what's the point? What were you guys going for when you decided to test out this change?
