None of the ratios, cooldowns, mana costs, damage amounts or ranges are set in stone. Chloria is really supposed to be building a bit like an Udyr.
For AD ratios, how do they not make sense? She isn't supposed to be high damage. In fact, I think her Q has too high of a scale.
That ult is a really good idea. I would tweak though, so that she grows thorny vines out of the ground, rooting the targets and causing them to take bleed damage on top of a flat amount of damage. Or something to that effect lulz.
