No, that isn't how it works. He still gets hit and affected by the cc. If he isn't applying the effect to him then that is a bug, not intended gameplay.
it does not apply the CC effect until the cast is over.
all if you are "casting" a spell you are immune to cc
channels can be interupted. but casts cannot
the CC will still take effect the instant it hits, but it wont stop the casting
i dont know you can find a table of skill cast times, (i had no luck on google myself)
but most cast times are either instant of VERY short
with the longest ones being trist rocket jump ez arcane shift at .25 seconds
and notably lux ulti at .5 second, and ez ulti at 1 second
which is why you can blitz pull lux or ez out of their ulti but it still fires from where they were standing
during these (like all casting) you are immune to cc (or rather more percisely, the will continue THRU the the CC)
the only way to STOP a cast is to KO them, (or at least i know you can stop lux' ulti if you KO her during the .5 second cast time)
like i said earlier though .. arcane shift and rocket jump are coded as "cast times" not "channel times" and therefore they cannot be interupted.
it not a "BUG" becuase that really isn't the correct term as it is doing exactly what it is coded to do.. but it IS coded incorrectly. as it should be considered a "channel" not a "cast"
