Summoner Spell diversity :)
Increase cleanse's duration by 1.5 seconds and make the caster immune to knock-ups and knockbacks for the duration, as well as removing grevious wounds.
Would be really nice to see a little diversity as far as summoner spells go. This change would probably most benefit the half-tank melee champs who haven't been recieving much love from Rito as of late; currently tele+flash or ignite+flash are the optimal choice for 99% of conventional toplane picks, and having an alternative that would add a more substantive mid-to-lategame effect by helping these guys PROPERLY shed off the peels of a well-composed team would be magnificent.
Would also be interesting as an alternative to heal for ADCS, who may chose to forego the instantaneous and reliable benefit that heal offers with something a little more strategic and lategame-conscious.
What do you think? Do YOU think that changes are in order for cleanse or any other summoner Spell currently available? 
{{summoner:2}} 
This spell has a niche use on ARAM. (because one use will affect the entire party.) However, Mana rarelly become a problem later in the game so it's usefulness drops off, unless it can mittigate the need for a major Mana item. (which should not happen.) The only time I would consider taking this spell is if I was a Mana hungry support paired with a Mana Hungry ADC.
