User blog comment:VirusVirus/Debate - New Forms of Crowd Control/@comment-1330314-20150607025129

The issue with Freeze/Sleep effects is that they tend to automatically create anti-combos: crowd control is generally used to pin down targets so that your team can focus them, but doing that an effect that breaks with damage would cause focus to break your crowd control. It also means that, for the break to have any significance, the base duration of the effect would have to be excessively long, which is never a good thing in a fast-paced game like League.

Disarm sounds like the only effect in game that Riot hasn't really presented as its own mechanic, even when it's implicit to certain abilities (, for example). It might be a bit too specific, since it would work super-well against marksmen and autoattackers but not against spell casters (sort of like a reverse silence, then), but then again it could still have a niche on a top laner.

Impale sounds a lot like, which is already an effect that is reducible by Tenacity. , and  all use the suspension effect, for example.

Busy hands sounds interesting, though I wonder how the effect would translate to gameplay. Attack speed slows in general aren't too visible right now, and extending the slow to cast times and channels sort of steps on the toes of silence effects.
