Improve the clarity of skills' description

I think that a lot of skills' descriptions need work to improve their clarity. Some example:

--- R --- FROM: Garen calls upon the might of Demacia to attempt to execute an enemy champion, dealing 175/350/525 magic damage plus 1 damage for every 3.5/3/2.5 Health the target is missing.

TO: Garen calls upon the might of Demacia to attempt to execute an enemy champion, dealing 175/350/525 magic damage plus 28.57 / 33.33 / 40% of target's missing health

--- R --- FROM: Galio channels for 2 seconds, taunting nearby foes and blocking 50% of incoming damage.After channeling, Galio deals 220/330/440 (+60% Ability Power) magic damage to surrounding enemies, plus an additional 5% damage for each attack he suffered while channeling. Max 40% bonus damage.

TO: Galio channels for 2 seconds, taunting nearby foes and blocking 50% of incoming damage.After channeling, Galio deals 220/330/440 (+60% Ability Power) magic damage to surrounding enemies, plus an additional 5% damage for each attack he suffered while channeling. Max 40% bonus damage: 308 / 462 / 616 (+ 84% AP)

--- R --- FROM: Dr. Mundo regenerates 40/50/60% of his maximum Health over 12 seconds. Additionally, he gains 15/25/35% Movement Speed.

TO: Dr. Mundo regenerates 40/50/60% of his maximum Health * (the amount is written here)* over 12 seconds. Additionally, he gains 15/25/35% Movement Speed.

NOTE: I know that Mundo can build for example to increase his healing, but I would like to know the flat amount not influenced by other factors.

And so on...
