Chaining the same hard CC should apply at reduced duration in ARURF

Specifically because of , but also others, being permanently hard cc chained by the same champion makes it almost impossible to kill them. Morgana being the worst offender by a long shot (now even worse since she can spam her W). So why not make it so after 2 times, the duration of the hard CC is reduced by a bit for every following application, resetting once the target champion has escaped and is OOC (or dead).

EX: First and second Morgana rank 5 Q snares for the full 3 seconds. After that it only snares the same target for 2.75, 2.5, 2.25, etc... (or whatever reduction rate is set to).
