Let's talk about Zyra's changes
As a former Zyra main who hovered around mid plat for most of last season, I felt like Zyra had a pretty solid identity, even though she was mostly overlooked as a mid laner. A well executed combo felt intentional and well thought-out, and her ability to stay at arm's length with a well placed snare somewhat made up for her squishy nougat center. Of course, there were some bugs, like the world's derpiest plants who would decide to stop attacking the enemy champion at random, and her passive, which always seemed like a bit of an afterthought.
I liked the idea of Rampant Growth as a new passive. It felt like something that would fit Zyra thematically, and help give a sense of having her plants slowly encroaching on an enemy. However, after playing a few games, something just feels off.
Rampant Growth is just too random. The fun part about Zyra was the strategic element - she couldn't just overpower you, the player had to choose their engages and their poke wisely, and avoid overextending for an automatic death by gank. Zyra's new passive seems to take away that element, and randomizes her power to the point where it weakens that core part of her identity. The cost of shifting more power into her passive hurts her tremendously as well. The E-W combo lost some of its distance, which cuts heavily into her ability to stay out of harm's way going into an engagement. In addition, the new radius for the Q just feels wrong. It fires horizontally while E fires vertically - lining up champions for a fantastic E means you're going to miss most of them with a well-placed Q, unless you can hurry off to the side and try to get it off quickly. But that obviates Zyra's identity as someone who needs to keep her enemies entangled at arm's length. She seems to need to be closer to the front to take full advantage of her combos now, and that drastically reduces her effectiveness in team fights.
Would love to get some other Zyra players' thoughts on this. I hope Riot doesn't intend to just let Zyra languish without any attention after her rework - I feel like she still needs some adjustments to really emphasize some of the core elements of her identity.
