Can we take a look at the coding of Warwick's ulti?

I was under the assumption that could not be disabled during his leap.. only after the suppression starts. this means there should be ZERO way the unit he is leaping at can interrupt his ulti WITHOUT getting it . (obviously another champ can CC DURING the suppression. but until it says "suppressed" he is IMMUNE to all forms of cc.

and yet.. i have been stunned while flying TWICE in the same game by i have been flipped DURING suppression BY a suppressed and (which cant be done BECAUSE THEY ARE SUPPRESSED!!!) and what makes this even MORE laughable is WHEN i was flipped there was a message that popped up that said "immune to CC" when it CLEARLY affected me as it stopped my ulti

AND in the same game as the i was leaping to their adc and somehow i suppressed the target directly BEHIND me.

so can we PLEASE take a look at the coding of his ulti?

and this isn't even including all the times i randomly miss the target when i land directly on them...
