New Warwick counters Yasuo ult, Vi ult and more
Something you may or may not know about the new Warwick: if you hold down your Q and swing around the target, you are immune to displacements while swinging. (Not immune to the damage, just the displacement.) Displacements includes knockups, knockbacks, knock-asides, and pulls.
So if you're laning vs 
, just swing around a minion every time he tries to knock you up. You might even be able to swing around Yasuo if you time it right.
However, you're not immune while dashing to the target, but you are while swinging around them.
The same tactic can be used against 
's ult as well.
Other notable reactable displacements you can cancel are:
Q ; 
R ; 
E ; 
Daisy knockup ; 
Q ; 
EQ combo ; 
Q ; 
R ; 
Q ; 
Q ; 
Q ; 
E ; 
R
Other displacements are either difficult or impossible to react to, so you will have to predict them.
Important note! Certain displacements have a stun attached (or are suspensions, which is not a displacement as far as I know). This means that you can cancel out the displacement effect, but not the stun attached to it.
These include, but are not limited to:
W (no stun on his Q though)
R (no stun on her Q though)
R (no stun on his Q though)
Q
Q and R
E
Q (no stun on her R though)
Final disclaimer: I have only tested this vs and . This covers nearly all cases, but there might be an interaction that is different from what I stated (for example, possibly R).
EDIT: Works on Q and Q
