You can knock your head against that wall all you want. It doesn't make it true. Pulling up a decent KDA or contributing a lot to assists does NOT make it competitive with the current meta. Nor does it make it as useful as the current meta.
Neeko can do the same thing as Morg's Q....... to an entire team. On a lower cooldown. Without Minion Block being a thing.
AP damage denial is shared by several champs now, and the CC mitigation while powerful, takes up a damage slot, and is a very linear skill with very little complexity.
W is literally NOTHING in its current incarnation. Many champions can literally out HP regen the damage it causes unless she hits Q, and then she has to be extremely fed to do much damage, and they have to not be building resist.
Ult literally kills her more than it contributes after about 13 minutes. After 13 minutes it's basically used as a last hit mechanism to champs who are low HP. If you try to use it as a team ult, you generally die, or you Zhonya's, they run out of your ult, and then you still die.
I'm definitely not saying she cannot win. Otherwise I wouldn't have started the thread. I am saying she is not complex, and you over-evaluate her strengths. It's like saying a Passive non skilling Janna is somehow competitive. Bullshit it is. But Janna often wins just by existing, and occasionally casting her shield. Only after about Plat Tier do you actually have to skill and set up complicated angles with her kit and actually use it.
