Remember the last time you used Cleanse?
Me neither.
Me neither.
The meta will shift and it will be used by every adc every game again...
Im sure if we could have a funeral for Lee, then it wouldn't be that crazy to have cleanse be better than it is.
One day, Riot will make it useful.
After they remove their star child
, of course.
I never used Cleanse ever, I really never have.
I use it when it makes sense. If you're taking heal every game because 'it's the meta' you're doing it wrong.
If you go into a match and the enemy team has Braum/TF/Ryze/Elise you MAY want to consider cleanse... that is two point-click stuns (I'm counting Braum as pointclick because it is applied on auto attacks), a point click root, and another stun on Elise. You NEED cleanse to avoid that.
Also, if the enemy laner is likely to take ignite (I see lots of Vayne/Leona carrying ignite), you should get Cleanse. It removes the ignite, and it also removes exhaust/crippling slows from Nasus or Braum.
It's super useful.
Honestly other summoners need to be brought into competition with the rest, and for god's sake we need Flash to be an innate ability on all summoner's like Recall is, because in EVERY circumstance flash is significantly better than other spells.
Well unless you're a champion that is SO mobile and SO broken that they should just be deleted from the game...

EG Altec used cleanse in a recent LCS game to great effect when he was playing Kog'Maw. It is useful in some specific cases. I linked the game below this paragraph. I recall Doublelift used it in an LCS game not too long ago as well and it saved him a number of times. I can't remember which game though.

Yep. I'm a big fan of taking cleanse against TF when I'm playing ADC. If you can get your support to take heal, it doesn't even give you a disadvantage in combat summoners, because cleanse removes the enemy's ignite/exhaust.
It's pretty great, you should try it out.
