Taliyah and The New Rylai's

I feel as if Taliyah has been a very unpopular champion, yet she is one of my favorites. Her kit is overall very fun to use and great for poking and kite. At least it used to be. Taliyah, with a 1.3% pick rate, has received so many unnecessary nerfs that ruined her gameplay in my opinion. She has always been one of the least played champions since her release, and I've only ever seen 1 Taliyah in a game, so why nerf her? Ever since her release, all of the follow nerfs have been applied: Q: -Took off the 50% extra damage to minions W: -Increased cooldown by 4 seconds at max level E: -Added 15% fallout damage per each consecutive mine -Reduced base damage by 30 at max level R: -Increased cooldown Rylai's: I'm going to write an explanation for this item to go along with the nerfs. The item itself was sort of overpowered, yes, but the nerf made it almost useless. The 20% slow has almost no effect, making it useless against the overpowered tank meta. On top of that, the stat drop, getting rid of 100 health and 25 ability power, significantly decreasing its power. The kite from the item is terrible now with almost no slow.

In my opinion, Taliyah has become very weak in her overall damage and kiting, making her not as fun to play and dropping her already low pick rate. In my honest opinion, I feel as if the nerfs should be reverted or Taliyah should just be overall buffed. Obviously I could be wrong, just looking for more opinions of the topic.

Edit: When discussing the overpowered tank meta, I more specifically mean champions such as Trundle, Vi, and Hecarim, that build 1 damage item and can one shot teams while being undying. I might make a separate post arguing the need for more Magic penetration / AP items. These champions are impossible to kill with the current magic penetration available, but for now the slow reduction from Rylai's itself is the problem that just makes the tank meta even more broken.
