CLEANSE needs new text

So, the other day, I was playing a ranked game against a Warwick and a Malzahar , so naturally I thought that grabbing cleanse instead of flash would be more beneficial (thinking I can just cleanse out of their ult and get away) (I was jungle ). So I go in to fight Malzahar , and to my infinite surprise cleanse did not get rid of his ult. I then proceeded to look up on lolwiki what they said the effect of cleanse was, and on lolwiki it says:

"Removes all disables (excluding Suppression) and summoner spells debuffs affecting your champion and grants 65% crowd control reduction for 3 seconds."

however, in game it says: "Removes all disables and summoner spell debuffs affecting your champion and reduces the duration of disables by 65% for the next 3 seconds."

In my honest opinion I would think that an ability that prevents movement and casting of spells would be considered a disable (hence suppression) therefore I feel very cheated by the text of cleanse when no where in it does it mention that it does not remove suppression. That has brought me to the conclusion that the in game text for the summoner spell really needs to be clarified to help prevent future people from taking a summoner spell that is considerably less useful in the situations that I needed it in.
