Can you update Mercury Treads description?

This is the description on the League of Legends wiki, this one gives alot more info than the description we currently have.

"UNIQUE Passive - Tenacity: Reduce the duration of Stuns, Slows, Taunts, Fears, Silences, Blinds, Polymorphs, and Immobilizes by 30%".

The reason i'm making this thread was because many times i didn't know for sure if Tenacity worked against Charms(I do now that i checked the wiki) but i really do feel like the "Tenacity" description should be updated, I'm also not sure if Tenacity is effective against Zoe's "sleep" CC.

Thanks for reading <3
