They took a step back from buffing her for now because of the changes to relic shield.
Riot thinks that it could be she was just performing weakly because she wasn't able to bully effectively with poke, since relic shield + fleet footwork + overheal negated it and the damage didn't stick.
If she keeps being weak after these changes now, they will look into buffing her again.
