Lets talk about Weird AP ratios on champions.
Personally, I don't understand why Riot gives some of these random ratios to champions that they will never use in a normal game.
Examples of ones that are "OK" in a sense because of their potential (cooldowns will be max rank of the ability): Jinx E: 270 Magic Damage+ 100% AP Ratio, 10 second cooldown (with some cdr this can go down to 6 or 5.5 with runes.) (if they step on it they are severely punished.) Vi E: bonus 90 Physical Damage + 70% AP Ratio, 8 recharge cooldown (2 total charges) (Hit opponents with 2 E's in short succession for 140% AP.) Sivir Q: 115 Physical Damage + 50% AP Ratio, 7 second cooldown (very unlikely in laning phase to do its high damage to champions because of minions, with some cd this ability can reach close to 3.5 second, where if the enemy is the only target this can hit them for 92.5% of her AP)
If you notice the only reasons why these ones make some sense is just because of how often they can be used with there high scaling.
Examples of ones that are nonsense (cooldowns will be max rank of the ability): Quinn Q: 120 Physical Damage + 50% AP Ratio, 9 second cooldown (similar to sivir's AP ratio, but heavily lacking in the power department due to its singe hit. But, has a short cooldown with cdr, around 5 seconds) Ashe R: 600 Magic Damage + 100% AP Ratio, 80 second cooldown (With cdr can go down to 48 or 37.4 with runes) Ornn R: 225-450 Magic Damage + 20%-40% AP Ratio, 100 second cooldown (With cdr can go down to 60 or 46.75 with runes)
With these ones it is easier to see why these ones are completely useless. Quinn Q: not high enough AP ratio to complement the cooldown. Ashe R: Amazing AP ratio, but way to long of a cooldown. Ornn R: Kinda a double whammy, Not a high AP ratio and a very long cooldown.
I feel like Riot adds some of these ratios to let players try and play a champion differently, however most of the time it ends up with the ratios only becoming viable in URF mode.
I am not implying that yes, you should play these champions in your ranked games with full AP builds, i'm just showing the potential that some have compared to ones Riot released with very little effect.
