[SUGGESTION] SS CLEANSE needs a BUFF/REWORK/REMOVED

Hi there,

I believe CLEANSE is the least used Summoner Spell in League.

It's problem's can be summarized in this quote "an ounce of prevention is worth a pound of cure"

Here's some of it's problems:

1. For it's utility it's on 210 second cooldown, same as Ignite and Exhaust.
2. CLEANSE is self-cast only.
3. The "3 seconds of 65% tenacity" after cast, is worthless in a team fight. ("Tenacity DOES NOT reduce the strength of slows, only the duration.")

Pick any matchup, and you will find a better Summoner Spell to use in any situation better than CLEANSE. I'm not going to start naming Champion abilities that are better than Cleanse, like Garen's Q for example.

I propose CLEANSE be Buffed, Reworked or Removed.

Buff Options: (same effects, different numbers)

1. Lower cooldown to 180s, similar to Ghost or Barrier
2. Scale tenacity per level (85% by level 18 for an example)
3. Tenacity duration increased to 5 second.
4. Can cast on self or on allied champion (not both)

Rework Options: (different effects and numbers)

1. Grants a Morganna's spell shield that Blocks spells or abilities, lasts for 3 seconds after cast.
2. Removes all current CC effects and Blocks incoming CC for 3 seconds, 210 second cooldown.
3. Grants invulnerability for 2 seconds, +1 for each nearby enemy champion 300 second cooldown.
4. Remove all current CC effects from yourself and nearby allies, 230 second cooldown

What do you guys think? Thoughts?
