I think this should be increased.

What happens when you are against a Sion, Brand, Fiddle, Galio, Ashe and Rammus?

Thats a perma stun/taunt in team fight...

Some champs dont have CC to rely on so they need to focus on damage output, but that is easily countered with MR and Armour (Aussie spelling). How is it fair then that we can only slightly reduce FIDDLES 3 SECOND FEAR o.O

you take cleanse and qss

huehuehuehue u want more tenacity on irelia? hue
6 champs op

def tree, another 10%, so does that mean with 35 tenacity, you reduce all cc by 45%?

inb4 better nerf irelia

Used to be 25, was buffed, 35% is A LOT. If 5 high cc champs all chain-stun you, well, they deserve the kill.

EDIT: 6 High CC champs

It's fine where it is.

BV, QSS and cleanse.
