There should be diminishing returns on cc
The insane amounts of cc some team comps can provide can be absolutely overwhelming.
Even while really fed its extremely difficult to be able to 1v2 2 champions that are with a negative kda if they have the right amounts of cc in abilities.
Being cc'd for 3 - 5 seconds every single fight doesn't seem really fair when that's plenty of time for even a bruiser or some tanks to be killed in.
Taking WoW as an example they introduced diminishing returns as a mechanic to prevent cc chains and locks. With the increasing amount of team wide cc this is something I am very surprised hasn't been added.
