She has been bugged for over a month now. This is ridiculous since you want to make her more reliant on her plant damage, but her plants don't attack. Fix her please this is out of hand.

SwoleMcSwag5 votesDoing the lord's work son. Thanks. Clearly Riot could care less about immobile zoning mages when there is the braindead ad diver meta going on. We wouldn't want intelligent strategic gameplay when people could faceroll the keyboard and left click on stuff.

Noor Sakata2 votesHer plants are bugged in many way " even positive one " When Ahri charms her while she has plants , her W is supposed to prioritize Zyra , but it goes to the plnats , as if the Plants are programmed as if they are Zyra herself , something related to this why she is bugged , if they fix it then they should know about this interaction with Ahri , probably it will help
Totally Not Jinx1 votesHer plants do attack, but I do believe they should prioritise champions rather than whatever is currently smacking them.
That being said, their range is seemed abysmally small and since they only spawn for 8 seconds or two auto attacks it's hard to even see what their range is without digging into champion data.
Frosted Tips7 votesThey are still bugged. They do still attack some to most of the time, but not like they should. I do agree with everything else you said.
5050BS12 votesHer Plants are bugged. In about 30% of her games the plants will not attack anything unless directed by a spell or auto attack even when they are right next to a valid target.
Iv had Ulted plants stand doing nothing until they die from the duration.
If 
turrets were bugged like Zyra's plants he would be hot fixed in a day or two.

That's really bizarre. I'm gonna watch her more carefully now because I don't recall seeing this problem, but if I do, I'll try and get feedback/signal boosts for you. I'm sorry that's happening [sg-soraka]

just wtf is this for. Heimer has had several bugs that took many actual years to be fixed.
Tenth Leper1 votesHappened to me once and a groupmate another time. I am DEFINATELY not gonna touch her at the moment.
Illabethe1 votesTheir range differs depending on whether they are Q or E plants. Q plants are 575 Range (350 self aggro range). E plants only have a 400/350 range.
If used correctly, Q plants have an effective range of 1375 from Zyra's origin.
Hardly "Dismally small."
I can 1v2 top lane with Zyra with this "dismally small" range.
Totally Not Jinx1 votesI get it, you had access to information that I didn't have. Cool.
Thanks for the info.
I run her as support which is a whole other animal and their range hasn't been my primary concern.
Illabethe1 votesInformation you don't have access to?
http://leagueoflegends.wikia.com/wiki/Zyra
And...... I play her as support too. It's really not. If anything, Zyra has a slightly easier time in support, because range champs can't 1 shot plants.
If you're having trouble getting Zyra's plants to attack, realize Zyra herself has a 575 attack range. If you miss a champion with a skill but proc plants..... auto attack the champion. The plants will follow suit. There are only a couple adcs who outrange Zyra's auto attacks.

Tell that to 
Illabethe1 votesMF can.
Corki can't, has a low attack range, (the bullets do 1 damage per tick)
Orianna is not an adc
Sona can with a skill procc'd, but that's one plant..... takes multiple hits to kill multiple plants. She's not efficient at it.
Teemo? his Dot does 1 damage per tick, not half the HP. It almost can, but like Sona, he's single target.
I'm surprised you didn't try to counter with Kai Sa.
And it's not like all these are "Squishy" or anything..... The spell innate damage can kill them, even if the plant damage doesn't.
Totally Not Jinx1 votesAlrighty then.
I was misinformed, that's a thing that happens.
I've never had a problem with my plants proc-ing, so I can't identify what this bug is that OP mentioned.
EasternBladeStar1 votesSmall indie company. No resources.
Or, rather, neither will nor interest. She isn't a flashy diver assassin.
Friendly Ram1 votesSorry zyra is fine. Her plants just went to hue school.
