I think her rework was all right, but the constant nerfs being applied to her broke the rework itself.
Lowering of her base damage, her early game AD/AP ratios on Q, and then changing her ravage from magical to physical screwed up the reworks intended aim.
The purpose of her ult was to be different, be a bit of a nuke but give her survivability to escape after assassinating someone, but she can't assassinate anyone after all the nerfs.
If anything, they should undo some of the nerfs to her early game damage, revert ravage's damage type, and then change her ultimate itself.
As it is, she is far too squishy, does too little damage, and has far too little utility to be considered tanky or an assassin worthy of use.
