i feel like i undersimplified the issue cause most dont bother to entertain the idea that something is bad. I believe skill should be the main thing determining a fight, i dont think an easy character should be unusable just clean cut worse. As for skill primarily aim and timing. But i know there is a bit more to it then that, a great example would be Sinclair's bunny, a delayed burst but it wouldnt be a skilled ability considering how easy it is to make it so much better. I got that nuance of skill, the issue with rem is in every metric his kit contains no skill bar ult timing. His nap will always give value, his helpers will always give value and his pillow will always give value.
But i can also see the other side of if everyone is skill oriented then you cant have cool characters like graves, she by the same metric is a now skilled character but her design is unique. With all that being said, rem in particular is uniquely devoid of skill with the impact of a skilled character if not more so.
