The CC reduction you can get from items and masteries is already quite strong (44.75% reduction), and any innate Tenacity past that tends to overscale (, for example, combined with the above can give up to 66.85% constant CC reduction). In general, while it's good to have Tenacity if you're up against a heavy CC comp, too much CC reduction effectively means the enemy team can do little to stop you. This used to be a huge problem on, because if he were fed he could just rampage around and kill whomever he wanted unimpeded.

While I'm not quite a fan of the current inclusion of knockup as a part of nearly every recent champion's kit, at least the knockup is usually tied to an ability that's either difficult to land or expensive to use: and 's knockups are telegraphed,  forces  to go all in, and / are on long cooldowns even in the late game.
