Illaoi's "test of spirit"

So im not sure what riot was thinking entirely with this skill.

My first issue with this skill is its cool down, for such a useful and by god annoying skill its cooldown is honestly a bit too short if you ask me (20 / 18 / 16 / 14 / 12). Ganks? Who cares if you don't get the kill so long as you grab the soul you can deal damn near their whole health bar mid game with one soul steal.

My second issue with this skill is the duration with which the soul remains, it remains for 10 seconds... I really can't comprehend why it lasts so long. You may say well hey you can just run out of the radius, but then wait you get a massive 80% for 2 seconds. With this i don't see why:

a.) your soul stays for such a long time because come late game your soul dies in a matter of seconds

b.) the slow seems unnecessary if you run away, maybe if your soul is killed that makes sense but why should there be literally zero counterplay to this skill... you get soul pulled you run you get slowed, you get soul pulled its killed you get slowed, its a lose-lose no matter what if you get pulled.

Lastly my biggest gripe, is the oh so stupid 1 full minute of tentacles spawning following your soul getting pulled. Once again the duration for which this skill lasts is honestly ridiculous. Yes its easy to bring it to an end by killing three tentacles (that is if your teammates actually read her kit and know to allow the person who's been struck to do this), but at the same time a full blown minute of this is honestly a bit excessive and once again the amount of counterplay to this ability is non existent. Your soul dies you get slowed and tentacles spawn for a minute, you run out of the radius and the same exact thing happens. Then provided its just you in lane and this isn't during a team fight you have to waste 30 seconds to kill 3 tentacles in order to avoid getting pounded while trying to farm and avoid getting struck by illaoi or getting your soul pulled out again, considering the ability will be on cooldown long before you can even kill 3 tentacles.

Personally I have no problems with Illaoi besides this skill, its a cool concept and a cool champ. However, this ability is honestly stupid to me with its lack of counterplay and ridiculous amount of utility with such short cooldowns, and minute long passive effects. But hey then again, riot almost always does this. Releases OP champ gets people to buy RP milk out as much money as possible for the chance of FreeELO then they nerf them to hell.

TLDR: if you run out of radius, no slow, no tentacle f-fest cause as of now it makes no sense regardless of whether you run or your soul dies you get that 80% slow and tentacle orgy for a minute long
