By those words (How do you move during a stun or suppression?) it could be perceived, at least by me, that either you don't know how Tenacity or CC Reduction works or you don't want the champion to be disabled.

In the optimism of thinking that you truly have doubts and want and answer for the question then read the following: Types Of Crowd Control. From the beginning you will have a summary of the types of CC, how they affect the target and how they can be removed; any further understanding of this can be seen by exploring the same page.

Additionally, Tenacity or CC Reduction works the following way: Decreases the duration of the disables by the percentage provided by the aforementioned statistics and this percentage increases multiplicatively  with other sources of the same.

In the negativism of thinking that you don't want your champion to be disabled nor debuffed then you are designing badly, any champion can be good, but none can be perfect.
