I don't think tanks need more CC... Saying you will give them more in Tank Update is SCARY
SCARY! Please think a bit before you do this... you don't know what it's like being chased by 40% cdr alistar+naut+skarner, watching your HP just drop for the next 30 or so seconds, unable to flash or move or cast a spell. I didn't believe it when it happened to me in a ranked game last season when tanks were op at one point.
There's already waaaaay too much CC in this game.
among others dont need slows.
