Why should I play Rek'Sai anymore

Rek'Sai has not had an easy life. She was released horrifically overtuned somewhat strong, and did get some nerfs to her damage. Then some more. then some more.

Now her Ratios are downright abysmal. She has one good AD ratio in her kit, and it's got enough caveats that it barely counts. Yes, 240% total AD true damage sounds AMAZING, but remember: It has no base damage, so you need to build some AD to do damage with it, and it's only 120% Total AD Physical if you have no fury, and you will have no fury because you entered the fight underground.

She's not a tank. She does not have the raw tank stats to be one, as any true tank has some steroid in their kit to make them hard to kill. She does not have any.

In addition, she has very limited CC. It's Point Blank AoE (PBAoE), which while it has its uses, is foiled somewhat by the per target cooldown. This means that Rek'Sai, who is played as a damageless tank, has ONE CC, that lasts for up to a second, and by the time it can be used again, the teamfight/gank is over.

So the only real reason to pick her at this point was for her vision control, which riot have now also nerfed.

So back to the title question. Why am I picking her? If I want a tank for CC, there's a whole host of them, like Gragas for example. If I want a tank that can also do a bit of damage, there's a lot of those too, like any that have % hp damage in their kit, such as almost all of them except Rek'Sai.

Please Riot, yes I'm biased because I'm a Rek'Sai main, but she is the first champion you released that I truly fell in love with. I'd love to One Trick Pony her through ranked, but at this point, she's so weak outside of pro play, that she doesn't do much.

Please, if you're 100% steadfast on killing tremor sense like this, let her do something else. Make her tankier, give her more damage back, SOMETHING.

You've slowly killed the most beautiful champion in the game, and I want something to be done before she's forgotten.
