Which is funny, because it's actually rather easy to garuantee the damage.

Huh...There's six minions...Alpha Strike hits four targets...I'll, uhm...Wait for three minions to die?

I'm a genius!

AP yi has one move .....

how is 400 dmg ever 6 seconds any better than ANY BURST MAGE OR ASSASSIN who can combo you for FULL health in less time than 6 seconds?

I'll take an AP yi with 1 move to vs against any day

I didn't know Karthus ult had a 10 second cooldown too. :P

Well seeing as they only nerfed his heal and AP Yi will still have ridiculous early game damage I think you are partly correct... and this all assumes the nerf go forward as they were seen on PBE, there hasn't been any official red comment that I have seen...

Ok he's meditating, we can counter him with ignite... no, he's healing a really stupid amount.
How about knockup or pushing him away. Nope, nothing.

BALANCED

Also gg, complaining about exact numbers when if anything will surely change completely it will be the numbers.

so many people do this then complain about getting poked out of lane by yi :/

The only thing thats GAREN - T'd is Demacian Justice

Karthus global is his ult you fool. AP Yi Q can destroy you from 1500 units on 8 sec cd and gets reset if his ult is active.

red commented that the duration would be reduced to 3 seconds

the 1.2 ratio is something that yi's can get by on, it'd just be less obnoxious if they go through with the nerf

Not entirely guaranteed but pretty f@#king close. As if the meager concession that 1 out of of every 4 Alpha Strikes doesn't hit your lane opponent really makes up for:

1) Ridiculous base damage and AP ratios
2) Free projectile dropping
3) Ridiculous range which, when cast on a nearby minion, places Yi well out of returnable harassment range when it finishes

Ap Yi laning is so g0d damned easy. Here's what it looks like:

Run around in back then Q
Run around in back then Q
Run around in back then Q

Accidentally take some damage? Run back to turret or bushes or stand between minions (if your opponent's CC doesn't avoid unit collision) and mediate back to full with 400% regen.

Jungle or side lanes come to gank? Hit R and run. Go back to lane, proceed to...

Run around in back then Q.
Run around in back then Q
Run around in back then Q

No skill shots, completely RNG reliant with 4 bounces that greatly increase the chance it will land more often than not. Unless of course, your opponent stands well behind minions and lets himself get zoned out of xp and gold.

AP Yi is complete easy mode.
