source (seems to be true)
TLDR
1.) break hard cc by pushing left + right mouse button together. (at the cost of stamina)
2.) hard CC shares the same immunity, that means stuns, knockbacks, fears, disorients, and “pull” effects all share the same immunity. the immunity is 5 seconds. if you break out of cc you get the immunity when you break out. if you dont break out, you get it when the cc expires.
3.) soft cc (roots and snares) have no immunity. 33% of your stamina by double tapping.
TLDR v2 -- stack the crap out of snares and roots. not sure about blinds (misses).
