Cassiopeia is still bullshit.
I know the meta is like laying shit in layers over top of each other. The top layer is the obvious stuff; lethality, Varus, Jayce, all that stuff. The second layer lies Cassiopeia and Leblanc.
Turning around in .01 seconds Faker style is not adequate counterplay to that ultimate. Additionally, miasma is the entire width of a lane... Makes it pretty hard to exploit her one weakness.
She wins mage matchups really hard because she can either farm freely or go highly aggressive... If she takes exhaust, she can further limit her opponents options.
She doesn't need boots and her CDs are not slowed by attack speed or anything, so DPS's only slightly slower under the influence of exhaust.
Rylai's is also highly exploitable. I just never liked champs that were good because the person has high APM. Even kalista had to time her hops to avoid stuff.
Almost all midlane mages have burst, and burst kills faster than DPS. The burst mage would win in an all in.
all will too
