Could we? The only way the stat is any bit useful is buying Merc Treads and Sterak's while taking the Tenacity rune. And that adds up to around 81% tenacity but in return that just makes it so that you can take one more cc than normal before you die. The overall damage in the game is so ridiculously high that a single cc is enough time to kill that target. Add in champs with multiple cc, which is close to everyone, and tenacity is just outright garbage. Please buff it so there isn't games that revolve around one team not being able to fucking play or add diminishing returns on cc in general. Even in pro play this is apparently. Too many times has a player WITH merc treads just outright lose to a champ that kept them locked down.
