As a Former Mid lane Zyra main, here's how you balance her for Mid, and Support.
Zyra's balance over time Zyra's been a fickle champion since her release. Her theme screams mid lane mage, but her gameplay screams bot lane Mage!
She needs a massive powershift
What I'd like to see happen to Zyra is a drastic lowering of her base damages, they need to be very low and her Ability power Ratios need to be much higher, this would force her into a position where she needs higher gold income to do the damage that she is known for, on top of this, her base armor and magic resist needs to be changed. A higher magic resist in the early game would help her against mages. if her Q had a longer range it would also allow for her to harass her enemy laner more.
How she can do damage, without being crapped on by enemy mages and assassins,
all the While not being an Oppressive Support
She'd become less of a lane bully in the early game if she had lower base damages and more Ability Power Scalings. She currently has a very short ranged ultimate as well (Which currently makes her lose out on a lot of her burst towards enemy mages and assassins). I think if it had a slightly longer range and a much lower base damage, with a faster spread time for the center to the edges, then she'd be able to win duels against other mid lane champions.
Support Zyra CAN and WILL live.
However, this doesn't mean that I want to kill Support Zyra completely. It's fun to play her and pull off these immense plays to support your team, but if you're going to play her support, it should be for the intention of wanting to help your team get ahead, not get ahead yourself.
It will make her a less oppressive support in the sense she won't be able to solo kill the enemy AD carry and Support without taking an immense amount of Ability power in her runes (and such, less armor and magic resist). She'll still be able to lock down the enemy ADC for her team with her crowd control, but won't be gaining an immense amount of damage from just building two items (
). With lower base damages and higher Ability power ratios. building flat magic penetration will not allow for her to be such a bully. Zyra has the Yasuo syndrome, people ban her just because they hate her, and that's because of her oppressive damage and ability to carry the bot lane by herself. However, I shouldn't have to play Zyra in the support role just to play my favorite mage to her full potential. So I ask you, balance team to experiment with more ways to balance her support and buff her mid, perhaps try my suggestions. Thank you.
