Why not buff the Health 
gives instead of the AP, since most of its users are battlemages making use of the slow in extended bouts?
would benefit more from extra health.
Even on champions with better AP ratios, it would be nice to have Rylai's as a bulkier option since it doesn't give any CDR and the slow doesn't really lend itself to maximizing burst.
Khristophoros6 votesWhat use is a tiny bit more health though, honestly? Add this passive:
You take 10% less damage from movement impaired enemies.
Boop Daddy 1 votesIt means you can soak up more damge. Which battle mages need. But that passive is funny and I like it. Tank Fizz would rise again tho. Not sure we're ready for that.

Mordekaiser may be the one exception, and he did stop building Rylai's specifically because of its lower AP, but even so his Q is the only one with a really remarkable ratio (84 AP or ~80 AD to double). W is below average, needing 333 AP to double its damage, and E is average, needing 258.
Still I'd rather have an extra 163 health on him than 20 AP for the same gold value. Or even 150 rounding down.
Ahristocats2 votesW has 120% AP ratio, average ap ratio in the game is 80% Ult gives you +4% max HP damage per 100 ap which is A LOT compared to EVERY single max hp damage spell in the game

The % scaling isn't the same as the ratio.
Evelynn has good AP ratios on her Q even though the %scaling is low because the amount of AP needed to double its base damage is not much at all.
When you have bad ratios, it's better to get magic penetration and cooldown reduction (And occasionally tankier items like 
), where those stats become less valuable and less rushed with lower ratios. 
can afford 
and 
because she doesn't get nearly the benefit someone like 
from rushing powerspikes like 
in terms of % increase to her damage output.
Evelynn is a good example of a bad AP ratio as well. Her ult has a 75% AP scaling, which is pretty decent, but is nothing compared to the skill's base damage of 150/275/400. In order to double her ult's damage she'd need 534 AP, so the damage her finisher does is relatively fixed compared to the damage of her other skills.
Compare AP to CDR for Eve's ult even. At max CDR of 45% (ignoring ultimate hat), evelynn efectively increases her damage output by that same amount, 45%, for a gold value of 1200. In order to increase her ult damage by the same 45%, she would need 240 AP, a value of 5220 gold. The raw listed AP scaling % doesn't tell the whole story of the AP ratios.
Long story short: CDR is massively undercosted.
Ahristocats1 votesno one cares about doubling the damage who the fuck cares about doubling a million of damage when a million of damage is already high?
THAT'S EXACTLY MORDE, his base damage are too high same for his ap ratios morde's damage are the highest in the game but he's immobile and lack of cc
it doesn't matter if he can't double W damage, the ap ratio is high and the amount of ap he gets combined with the high base damage will be insane

Ifneth1 votesTaliyah scales alright with AP, but her main damage source during the mid and late game is the burn from Rylai’s and Liandry’s on her Q. She could use a little more HP to step forward for her combos.
BobaFlautist1 votesI mean maybe champions with good ratios will consider it now that the ap gives is less shit...?
Denims Wrath6661 votesoddly enough, bad idea. one sleeper that not many know about is 
with rylais. you buff the hp, thats gunna be a META rush on him. no thanks. im ok with it being sleeper.
