why hasnt CoS been nerfed considering a bunch of the other things have listed here or is the information on wiki just wrong or is the wiki just wrong?

Wiki is wrong.

It happened July 2001 - http://www.tski.co.jp/baldio/patch/20010627.html

figured as much.

Have we updated the wiki to reflect the inaccuracy? ;)
