Riot, why no Soraka buffs?

I felt like posting about something that in the grand scheme of things, I don't remotely understand. That is why Soraka needs more banana damage and higher regen in exchange for the clarity nerf of her passive on her champion profile page.

Let's compare two champion passives, in terms of clarity: Our space goat goddess: http://gameinfo.na.leagueoflegends.com/en/game-info/champions/soraka/

Salvation Soraka runs faster towards nearby low health allies.

As you can see, it doesn't tell you at what distance it will activate, how low of health the ally must be to activate, or how much movement speed it will grant.

Lets take a look at a giant ugly monster frog: http://gameinfo.na.leagueoflegends.com/en/game-info/champions/tahmkench/

An Acquired Taste By damaging enemy champions with basic attacks and abilities, Tahm Kench builds stacks of An Acquired Taste on them. At three stacks, he can use Devour on an enemy champion.

<What does Devour do? Just scroll down to find out!>

Devour Cost: 90 Mana Range: 250 Tahm Kench devours a target, dealing a percentage of their maximum health as magic damage. He can spit devoured minions and monsters out as a skillshot that deals magic damage in an area upon impact. Devour a target for 4/4.5/5/5.5/6s (half that for enemy champions.) Enemies are dealt 20/23/26/29/32% (+[2% Ability Power]%) of their maximum health as magic damage (maximum of 400/450/500/550/600 against neutral monsters). Enemy Champions: Requires 3 stacks of An Acquired Taste to be devoured. While holding an enemy champion, Tahm Kench is slowed by 95%. Allied Champions: While holding an allied champion, Tahm Kench gains 30/35/40/45/50% movement speed toward enemy champions (halved when not moving toward enemy champions). Minions and Monsters: Reactivate to spit them, dealing 100/150/200/250/300 (+60% Ability Power) magic damage to targets hit.

I suppose I'll end this thread with a practice poll. I haven't made one of those before.
