Rebalancing summoner spells:

Clairvoyance: Reveals an area of the map for 5 seconds. Clairvoyance also reveals wards. Cooldown: 60

Explanation: Improved functionality and a definite advantage over the trinket.

Clarity: Restores 40% maximum mana to you and your nearby allies. Reduces the cooldown of your non-ultimate spells by 35%. Cooldown: 180

Explanation: Adding an in-fight component to a pure sustain spell. It helps DPS casters more than ignite, while burst casters still ebenefit more from ignite.

Cleanse: Removes all disables and summoner spell debuffs affecting your champion and lowers the duration of incoming disables by 65% for 3 seconds. All enemies around you get stunned for 1 second. Cooldown: 210

Explanation: Adding a more aggressive component which also creates a timeframe to get away from assassins / bruiser who jump at you.

Ghost: Your champion passes through any unit and moves 33% faster for 8 seconds. During the first 4 seconds you can also through walls. Cooldown: 210 (Boots now reduce cooldown instead of increasing the speed)

Explanation: Makes up for one of the most severe disadvantages Ghost has over Flash, while Flash still is better for Spell dodging and initiations.

Revive (reworked): After a 5 second delay you spawn where you died with 55% health and mana. If several revive spells are used in a certain area (2000 radius) the health restored is reduced to 35%. Cooldown: 210s
