attack speed per level was gutted, was 3 or something now its 1,
Didn't happen. Her attack speed is exactly the same as it ever was.
base true damage removed on her silver bolts,
With the percentage increased to levels that are equal or even superior damage for most of the game.
botrk nerfed and cost increased,
This might matter more if she still needed BotRK. With the Shiv/Firecannon combo, BotRK would have been a thing of the past even if it wasn't nerfed. That combo is thankfully getting nerfed next patch (mostly because of Vayne abusing it), but it does exist right now.
The 3 AD nerf and the lowered AD per level is really the only thing that stuck, and that's not enough to make up for the things she got. She's just as strong as she ever was. If MF and Quinn hadn't been made stupidly powerful, she'd be a contender for best ADC right now.
she honestly doesnt feel like total cancer to me anymore
That's a very positive attitude to have, and it's generally the way you should be feeling about her. It didn't change because of her actual balance state though. It's all perception.
