caitlyn trap too abusable with no active retrap timer

So many champions in this game have a time limit cap that says how long the same champion is allowed to be stunned. However, Caitlyn's stacks break all fairness if she's with any type of champion who has an additional snare or stun since her's literally has no timer on how many times a champion can be hit by this single skill.

Example:

lands a snare. hits the stun. Immediately after stun enemy champion is snared already due to stacks and no time restriction on snare.

This type of skill allows zero counter play. It's one thing to be chain cc'ed by multiple champions. It's another to be chained by the same skill from the same champion. This just happened in our last game where even our tanks were just stuck in 1 spot while Caitlyn laid trap after trap in the same area on the same champion because there was enough snares/stuns it just let her spam it.

requires 4 skills to produce a stun. has a longer cooldown and requires multiple hits/wall. requires a skill to hit, AA, and has a longer cooldown. cannot retrigger the same champion until timer resets. cannot retrigger freeze on the same champion until timer resets.

Why does Caitlyn not have a timer then?
