Actually, it's impossible to have 100% CC reduction, since it multiplies, instead of adding.

It's like armor. The damage reduction is 50% with 100 armor, but it is 66% with 200 armor, and 75% with 300 armor.

So if you have, say, 20% CC reduction, and you get 20% more CC reduction, you will actually have 20% + 20% of the remaining 80%, and that is 20% + 16%, so you will have 36% CC reduction. If you add another 20% CC reduction, you will have 20% + 16% + 20% of the remaining 76%, and that equals 20% + 16% + 15.2%, and you would have 51.2% CC reduction. If you continue this equation, you can gat to 99%, and then it just goes to decimal numbers.

So, no, Irelia can never be "invincible for CC", or any other champion, for that matter.

I hope this answered your question.
