Chain CC on Zilean intended?
I've been poking around with Zilean and once you get 99% slow, you can freeze someone in place for 6.5 seconds. A 2.5 second 99% slow (basically a root), followed by a 1.5 second stun from landing two bombs (obtained easily because the champion is rooted), followed by another 2.5 second 99% slow (because you used Rewind to proc your second bomb). The 99% slow is also a targeted spell and not a skillshot, so there is no way to dodge this.
This rotation can be used every 15 seconds from when Zilean hits level 9 and obtains his 99% slow.
I'd like for this to be the correct playstyle because it's really fun and really powerful, but it feels a little overpowered.
