The only useful cleanse ability is an instant one. Be warned though, it's powerful enough that it's worthy a full ability in itself, if it's not an ult.

Now that you're getting me thinking though... How about (unrelated to this rework proposal, which I to be honest haven't read past the Q yet) an ultimate for Taric, that simply instantly cleanses all cc from allies (or everyone?) in a 600 range (aka Amumu, Galio, Fiddlesticks, etc ult) around himself, can be used while cc'ed? I don't know why exactly, but it feels like it fits.
