What cc does talon have?
Or diana?
Or kayn?
Or kha??
Anything that can interrupt offensive or defensive actions, sometimes in addition to movement, is considered hard crowd control.
Anything that interrupts movement is soft crowd control.
On the basis that in soft cc, at least you can fight your way out of your inability to move (like when you're rooted, snared, or slowed).
Whereas hard cc, you're at the whim of your tenacity and the duration of the condition. No abilities, basic attacks, or summoner spells unless stated otherwise.
And although brief, they still count.
Diana's Moonfall has a draw, or applies an airborne condition on enemies to move towards her.
Kayn -> Rhaast's Bladereach can apply an airborne condition to enemies affected.
Kha doesn't have hard crowd control.
Kassadin's Null Sphere however applies a short interruption that halts an enemies channel immediately. Although it doesn't prevent them from moving, it prevents them from acting offensively or defensively from it, maybe not entirely but it disables a wider array of options than a root or a slow could.
