So, you probably expect me to rant about how you can be double-CC'ed, triple-CC'ed, chain-CC'ed and so on, since you don't get CC immunity until the CC animation or your break-free animation ends.

Well, not today. Today I got pulled out of Aleswell maingate by the Swarm Mother set into a large enemy zerg, but a Javelin threw me right back into safety after some meters. Thank you, horrible CC mechanics!
