Why are Zyra's cast times still so long?

Seriously, we are curious why she is played exclusively support, when she's just ridiculously slow for mid and her range! Yes, there are other slower champions, but those possess a range that helps them to survive!

Her spells and cast times are so slow that you don't even need boots to dodge them, even when they are already cast. Sure, it's way harder in botlane where there are two enemies to focus on, but in the midlane, where 4/5 champions have dashes and other mobility spells, you need to have godlike prediction (compared to other champions) and hope they are bad. It's like playing against Yasuo reverted, because not being able to influence the trade comes from your champion, not enemy, but still from the enemy player.

Slowly she has been destroyed again because of the support role and is now unplayable. You try to cast Q on max range and only thing enemy needs to do is to walk to you, because not only he'll easily dodge the spell, but also gets in their range (if they need to, otherwise they won't even have to dodge) and actually get to you before the cast time ends.

Now I'm not asking for her ranges to get buffed, no, god that would be disgusting. I wanna ask, NO, I BEG! Can please be Zyra's cast times reduced? 0.75 s on E is just awful. The projectile itself is slow, stilly very easy to dodge, but PLEASE make it so it means she instantly dies if she tries to cast it, because before she's able to move again, Fizz's ult will reach her two times!

0.75 s --> 0.6-0.4 on E Now I'm not sure and can't find the exact cast times of other spells, but they feel clunky, too.

EDIT: Wait what? Where is the hate? Do people really agree with me for once? plantgasm
