Suppression, Can anyone explain what this is?

[quote=Yeldarb]Basically, What is suppression? I hear people talking about it on the general forums but I have no idea what it is. Is it a new summoner spell? Is it just a new name for a stun? Or is it something else? Please, anyone, help![/quote]

[quote=Diego]I believe that it's basically what people would call a perma-stun. For example, when Malzahar used his ult you would be able to cleanse it off or if you had merc treads it's duration would be reduced. With suppression, anyone's ult like Malz, Warwick, Amumu, Urgot, etc. their ultimate cannot be reduced by a percentage or cleansed all together.[/quote]

[quote=Yeldarb]oh ok. has this already been implemented or is it an upcoming change? Ive just been hearing a lot of talk about it on the forums lately (LoL forums)[/quote]

[quote=caucheka]all i know is that mal's ulti has suppression. idk anything else.[/quote]

[quote=Diego]It's effective as of the Miss Fortune patch. (Which surprisingly includes the 72nd Ezreal nerf.)[/quote]
