Is Rylai's too strong?
I feel like many of the annoying mages are in this state because they are able to abuse rylai's for a permanent 40% slow. Take Azir for example, if you step within his 2k range and you aren't playing a free dash champion, you can't escape because of the slow, even if you use ghost or another MS buff. I think it would be more fair as a 30% slow instead or if there was a CD "can't apply to the same target again in 4 seconds."
