If Karthus blocks one route with his wall, you can either run through it, run towards Karthus, or attempt to run a third route for freedom (or flash/blink though).

Only a good location and replacement from Karthus's wall will u find a situation with only two bad options but that requires good skill from Karthus and his teammates to create a situation like that.

And once again, the reason I hate it is because how it effects the enemy. Abilities like what you purpose create the sense for the enemy that they have no options while giving false options. A straight up stun, though may give less options, has a clear impact to the player without informing the enemy fake information. You're giving them the ability to run away, but the moment they try, they will get punish harshly.

P.S: If you really want to find a skill that has such a style like your's, look at. This doesn't mean I approve of a spell like this, but at least the punishment isn't as harsh as yours.
