2. Zyra
The ‘Rise of the Thorns’ mostly had changes to her plants. While her seeds will no longer grant vision of anything, and leveling up her Rampant Growth (W) will not give cooldown reduction, seeds now passively spawn around Zyra. Further, plant life scales with levels.
More interestingly. her Deadly Spines (Q) now fires in a rectangular shape, as opposed to its previous circle, covering far more ground. While the shape change might not seem like a big deal up front, it contributes significantly to her ability to zone enemy champions. In combination with the increased number of active plants, this ability will really make Zyra a thorn in your side. Already a mage with one of the best defensive skill sets, this re-made Zyra will be even better at controlling space, while sacrificing a little bit of upfront damage.
