Yes she's still ging tank, and yes, buffing her AD ratios will not change that.
However, going the ekko way and nerfing her utillity ontop of base damage while boosting her ratios will just cause her to be totally useless.
The way her kit works, she desperately needs tankiness to funktion past the early game.
Her damage is very delayed, her gapcloseing is very telegraphed, her mobillity in fight is very limited, and she needs to get right into the middle of a team to get things done, if she's not tanky, she just gets popped befor doing anything.
If they want her to built agressive, then she needs ALOT more base survivabillity, else she'll never go more agressive than BC+Titanic or maybe a wariors into hextrinker into tank if snowballing early.
