Can I get an explanation regarding Poppy?

It's clear they want to push her more towards being a bruiser than a tank, but what I want to know is why? And why, since that's the aim, are they giving her passive range and cooldown adjustments instead of a damage scaling? Especially when it isn't reduced by CDR, one second doesn't mean anything.

She hasn't been performing well enough to warrant nerfing her as a tank. And she certainly doesn't have the kind of synergy with any new runes to warrant changing her into a fighter. It makes little sense.
