How do people seriously think Ashe will be OP now?
Yeah, she slows a lot, but every ADC does that with Red Buff. And the extra damage? With IE and bullshit luck an ADC will do 250% damage on plenty of autos, her damage is at least consistent.
And also, don't forget Ashe has like 7 move speed. I'm pretty sure Steven Hawking could outrun her.
