Reinforced walls.
Champions can't dash/flash/pass through these walls
- the outer edges of the walls, specifically in top lane. Players rotate way too fast, or jump through walls and squash split pushing way too easily.

But Kayn! In reality if you want to split push, you need to set up a good vision field.
Just remove the unnecessary passes-walls flag on nearly all dashes.
As a rule of thumb if the animation does not involve leaping high into the air, it should not be able to cross walls.
Looking at you 
.

's third Q make sense and are fair.
and 
make no sense animation wise, but are fair. Riot could solve the animation weirdness by just creating a secondary dash animation for when crossing walls.
you can even dash through walls with kayn
